27 Fun Facts About Pee-wee’s Playhouse

Shout! Factory

Thirty years ago, on September 13, 1986, Paul Reubens introduced America’s youth—and millions of its young-at-heart adults—to a new brand of Saturday morning programming when Pee-wee’s Playhouse made its triumphant debut. Over the next five years, Reubens—as his slim suit-loving, bow-tied alter ego—and his merry band of playmates (human, puppet, and otherwise) would go on to revolutionize the face of children’s television and pick up dozens of award nominations in the process. Thanks to Shout! Factory, you can own all five seasons of Reubens’s groundbreaking series on Blu-ray with Pee-wee’s Playhouse: The Complete Series. To celebrate the show's anniversary, we chatted with Reubens and uncovered some things you might not know about Pee-wee’s Playhouse

1. PEE-WEE HERMAN WAS BORN A GROUNDLING.

Pee-wee Herman “came about from an extended improv at The Groundlings,” Reubens says of the character’s origin. “We were just given an assignment to come up with a character that one might encounter in a comedy club and I came up with Pee-wee Herman.” Pee-wee’s first stage appearance was in 1977. 

2. “PEE-WEE” WAS A HARMONICA.

Reubens says the character’s many distinctive traits were "a bunch of stuff all mixed in together. The voice came from a stage production that I was involved in. And then the name came from a kid I knew who was kind of off-the-wall. The name Pee-wee came from a little harmonica I had that said ‘Pee-wee’ on it. I loved the idea of a nickname, because it sounded so real to me. ‘Pee-wee Herman’ sounds like a name that is so odd, how would you make that up? If you were going to make up a name, you’d make up a better name. It seemed real to me; it was a nickname with a last name that’s also a first name… And it went hand-in-hand with what I wanted to do, which was to make people think this was a real person, not an actor.” 

3. PEE-WEE’S SUIT WAS A LOANER. (BUT NOT A REBEL.)

“The director and co-founder of The Groundlings, a man named Gary Austin, loaned me his suit, which I never gave back,” Reubens says of Pee-wee’s now-iconic gray suit. “Someone else gave me a kid’s black bowtie, which I later changed out for a kid’s red bowtie. And the white shoes were mine. That’s just sort of what I put on and I had success with it so I thought, why mess with it? If it ain’t broke.” 

4. PEE-WEE GOT THE GIRL ON THE DATING GAME.

Pee-wee’s debut onscreen appearance occurred in 1979, when he made his first of three appearances on The Dating Game (totally in character). “That was a little test experiment I was doing early on,” Reubens recalled to Interview Magazine. “I went to a cattle call audition for The Dating Game, and before I even got home they called me back.” On one occasion, he even won the date! 

5. PEE-WEE WAS AN ANGRY HOTEL CLERK IN CHEECH & CHONG’S NEXT MOVIE.

In 1980, Pee-wee made his first big-screen appearance as a not-so-sweet hotel employee in Cheech & Chong’s Next Movie. 

6. THE PEE-WEE HERMAN SHOW WAS A FIRST FOR THE GROUNDLINGS.

On February 7, 1981, Reubens helped to take The Groundlings in a new direction when he premiered The Pee-wee Herman Show at midnight, a stage show that became the group’s first piece of alternative format programming. Shortly thereafter, it moved to The Roxy on Sunset Strip, where it ran for five months. But it wasn’t an adults-only kind of thing; matinee performances proved to be fun for the whole family. Miss Yvonne, Captain Carl, Jambi, Pterri, and Clocky are some of the characters that were there from the beginning. 

7. IT DIDN’T TAKE LONG FOR HBO TO COME CALLING.

Pee-wee gained national attention courtesy of HBO, which aired a taping of one of the show’s performances at The Roxy in 1981.

8. PEE-WEE KICKSTARTED TIM BURTON’S CAREER.

Following the success of The Pee-wee Herman Show, Warner Bros. approached Reubens with the idea of making a Pee-wee movie. Though the studio originally had another director in mind, several people mentioned Burton to Reubens one night at a party. “I screened Frankenweenie and I spoke to Shelley Duvall who was a friend of mine who was in Frankenweenie,” Reubens recalled to Ain’t It Cool News. “I knew Tim was the director about 15 seconds into Frankenweenie, like the second or third shot of it. I was looking at the wallpaper in this bedroom and the lighting and just going, ‘This is the guy who has style and understands art direction.’ Those were two really important things for me and my baby, I guess, and you know it just happened to luckily all work out." 

9. PEE-WEE’S BIG ADVENTURE CLEANED UP AT THE BOX OFFICE.

Shot on a budget of approximately $7 million, Pee-wee’s Big Adventure earned nearly $41 million at the box office. Which, not surprisingly, led to a sequel: On July 22, 1988, Big Top Pee-wee hit theaters. 

10. THE ORIGINAL CONCEPT FOR PEE-WEE’S PLAYHOUSE WAS AN ANIMATED SERIES. 

Following the financial success of Pee-wee’s Big Adventure, CBS approached Reubens about creating a children’s series around the character—only they wanted it to be animated. “I'd had the stage show originally, so I was much more interested in doing something closer to that, something live-action,” Reubens recently told Rolling Stone. “So when they suggested doing a cartoon, I said ‘I'm not really interested in that; let's do a real kids' show.’ I was a big Howdy-Doody freak growing up—I was actually on one show when I was a kid, in the audience—and was more interested in doing something like that. Howdy-Doody, Captain Kangaroo, a lot of the local kids' shows that were on a long time ago—those were the influences.” 

11. CAPTAIN KANGAROO WAS A PEE-WEE FAN.

Bob “Captain Kangaroo” Keeshan was such a fan of Pee-wee’s Playhouse that he reviewed one of the show’s earlier video releases for Entertainment Weekly in 1996. In it, he cited the series’ “awesome production values; with the possible exception of the Muppets, you can't find such creativity anywhere on TV,” and went on to say that “star Paul Reubens is an absolute genius.”

12. REUBENS WAS GIVEN FULL CREATIVE CONTROL OF THE SHOW.

Throughout its five seasons, Reubens maintained full creative control of Pee-wee’s Playhouse and says there were only a few occasions where the network asked that something be changed. “In the first episode, the network said ‘You can't stick that pencil in that potato, because pencils are sharp, and you might encourage kids to stab things,’” Reubens recalled to The A.V. Club. “So we didn't do that. Let's see. There was an episode they got a letter about, where there was a fire in the playhouse, and a firefighter showed up and he and Miss Yvonne were flirting, and he said ‘You have to have a smoke detector,’ and she said ‘I have one in my bedroom, above the bed.’ They asked us to change that for subsequent airings of the show, so we went in and looped dialogue over it, so instead, she said ‘I have one in my kitchen.’ I put it back to the original version for the DVD release. There was a shot of a bathroom door that we held for a really long time, and you could hear Pee-wee peeing. They asked us to tone the sound of the peeing down, and add a score so it was a little less graphic. All the changes they asked us to make seemed really reasonable to me, and we accommodated them. I think in 45 episodes, there were only maybe three other changes they ever asked for.” 

13. WITH CREATIVE CONTROL CAME FINANCIAL RESPONSIBILITY.

“Originally, I lost quite a bit of money on Pee-wee’s Playhouse,” admits Reubens. “I was responsible, financially, for Pee-wee’s Playhouse. So when it went over budget—not if it went over budget, when it went over budget—that came out of my pocket. I don’t want to mention a figure, but we had one season that was over budget by a lot of money. I’m a little bit of a perfectionist. Not a little bit: I’m a perfectionist … I want to rebuild the whole Playhouse door if it’s too big or the wrong color. So I feel like I’m a great producer, but I also have distinct limitations in that department because I will always spend more money and not sacrifice quality. So it went over budget a lot. Like, every season.”

14. PEE-WEE CLIP SHOWS WERE NOT A SIGN THAT REUBENS WAS LOSING INTEREST.

Reubens says that some of the ways they worked to get the budget back on track in the last two seasons was to do a couple of clip shows. “Somebody just wrote somewhere that [the clip shows] were a good indicator that I had lost interest in the show by the last season," he says. "And it’s so far from the truth. I lost interest in having to pay all this money out of my pocket and so I paid way more attention to the line producer, who was a great man who came up to me all the time and said, ‘You can have this or this,’ or ‘If you want this, then this is how you have to do that.’ I trusted him and he was right and he was the guy who brought in the last two seasons on budget.”

15. CYNDI LAUPER SANG THE THEME SONG.

Though the series’ theme song is credited to Ellen Shaw, Cyndi Lauper admitted in her autobiography that she is the voice behind it.

16. THE PLAYHOUSE WELCOMED A NUMBER OF SOON-TO-BE STARS.

A number of burgeoning stars got their starts on Pee-wee’s Playhouse. Among them: Phil Hartman, S. Epatha Merkerson, and Natasha Lyonne. Both Laurence Fishburne and Jimmy Smits also made early-career appearances.

17. ROB ZOMBIE AND JOHN SINGLETON WERE PRODUCTION ASSISTANTS.

The Playhouse had plenty of talent behind the camera, too. Five years before he wrote and directed Boyz n the Hood—for which he earned two Oscar nominations—John Singleton was a P.A. on the Playhouse set. Around the same time he formed White Zombie—and 17 years before he moved into the director’s chair with House of 1000 Corpses—Rob Zombie held the same title. 

18. S. EPATHA MERKERSON COULDN’T LOOK AT REUBENS.

In the new Blu-ray collection’s special features, Law & Order star S. Epatha Merkerson recalled how hard she laughed the first time she saw Reubens dressed as Pee-wee. “And from that point on I know that Paul knew that he could make me laugh. And he tortured me,” she recalled. “At one point the director came over and said in this very low voice, ‘I need to get this shot. How do I get this shot?’ And I said, ‘Well then I can’t look at Paul…’ I really thought I was going to lose the job!”

19. PHIL HARTMAN LEFT AFTER ONE SEASON TO JOIN THE CAST OF SNL.

Phil Hartman, Reubens’ longtime friend and collaborator (they co-wrote Pee-wee’s Big Adventure together), left the Playhouse—where he played Captain Carl—after the first season to join Saturday Night Live.

20. MISS YVONNE’S HAIR WON AN EMMY.

Two Emmys, actually. One in 1987 and another in 1989. The show won a total of 15 Emmys throughout its five-season run. 

21. JAMBI SPOKE GIBBERISH.

On the Blu-ray collection, writer John Paragon describes Jambi’s famous “Mekka lekka hi mekka hiney ho. Mekka lekka hi mekka chahny ho” chant as gibberish. “So I’m in The Groundlings and we’re doing a sketch and it’s customers in a Hawaiian restaurant and I’m wearing a Hawaiian shirt and doing Hawaiian gibberish. So that’s where that line came from. It was supposed to be bad Hawaiian.” 

22. LAURENCE FISHBURNE HAD A DARK TAKE ON COWBOY CURTIS.

During his original audition for Cowboy Curtis, Laurence Fishburne didn’t get the note that the tone of the show was rather silly. “I was in the D.C. area making Gardens of Stone, and I got this call that Paul wanted to see me,” Fishburne recalled to Entertainment Weekly. “I had almost no hair on my head because I had been doing this military picture. I [auditioned as] a Yul Brynner-esque kind of cowboy—very dark and serious. [Reubens and Paragon] both looked at me like, 'Could you lighten it up?'"

23. SEASON THREE HAD JUST THREE EPISODES.

Because of a 1988 strike by the Writers Guild of America, the third season of Pee-wee’s Playhouse is comprised of just three episodes—two regular episodes and one primetime special, Pee-wee’s Playhouse Christmas Special.

24. PAUL REUBENS IS NEVER CREDITED AS SUCH.

To keep the idea alive that Pee-wee Herman is indeed a real person, Paul Reubens’ name does not run in the end credits. They simply list “Pee-wee Herman as Himself.” 

25. BY 1990, REUBENS WAS READY FOR A BREAK.

“I just politely said ‘No,’ Reubens recalled to Entertainment Weekly about his decision to take some time off after five seasons. “It was time to take a year off. I had actually made a list of things I wanted to do—learn Spanish, learn to play the sax—and I never hit one of them. At the end of [1990, while season 5 was airing], I decided I was going to take a second year off.” 

26. PEE-WEE CAME TO BROADWAY IN 2010.

On October 26, 2010, Pee-wee was back—this time on Broadway—for a limited-run stage show.

27. DON’T ASK REUBENS TO NAME HIS FAVORITE PLAYHOUSE CHARACTER.

“Oh, how can you ask me that! Now you know that I can’t answer that! If I said one person then all the rest would be angry,” Reubens laughs. “And I still love all those people and they’re all my friends. I still see every one of those people so I couldn’t. I couldn’t do it.”

10 Scientific Benefits of Being a Dog Owner

The bickering between cat people and dog people is ongoing and vicious, but in the end, we're all better off for loving a pet. But if anyone tries to poo-poo your pooch, know that there are some scientific reasons that they're man's best friend.

1. YOU GET SICK LESS OFTEN.

If cleaning commercials are to be believed, humanity is in the midst of a war against germs—and we shouldn't stop until every single one is dead. In reality, the amount of disinfecting we do is making us sicker; since our bodies are exposed to a less diverse mix of germs, our entire microbiome is messed up. Fortunately, dogs are covered in germs! Having a dog in the house means more diverse bacteria enters the home and gets inside the occupants (one study found "dog-related biodiversity" is especially high on pillowcases). In turn, people with dogs seem to get ill less frequently and less severely than people—especially children—with cats or no pets.

2. YOU'RE MORE RESISTANT TO ALLERGIES.

While dog dander can be a trigger for people with allergies, growing up in a house with a dog makes children less likely to develop allergies over the course of their lives. And the benefits can start during gestation; a 2017 study published in the journal Microbiome found that a bacterial exchange happened between women who lived with pets (largely dogs) during pregnancy and their children, regardless of type of birth or whether the child was breastfed, and even if the pet was not in the home after the birth of the child. Those children tested had two bacteria, Ruminococcus and Oscillospira, that reduce the risk of common allergies, asthma, and obesity, and they were less likely to develop eczema.

3. YOU'LL HAVE BETTER HEART HEALTH.

Everything about owning a dog seems to lend itself to better heart health. Just the act of petting a dog lowers heart rate and blood pressure. A 2017 Chinese study found a link between dog ownership and reduced risk of coronary artery disease, while other studies show pet owners have slightly lower cholesterol and are more likely to survive a heart attack.

4. YOU GET MORE EXERCISE.

While other pets have positive effects on your health as well, dogs have the added benefit of needing to be walked and played with numerous times a day. This means that many dog owners are getting 30 minutes of exercise a day, lowering their risk of cardiovascular disease.

5. YOU'LL BE HAPPIER.

Dog owners are less likely to suffer from depression than non-pet owners. Even for those people who are clinically depressed, having a pet to take care of can help them out of a depressive episode. Since taking care of a dog requires a routine and forces you to stay at least a little active, dog owners are more likely to interact with others and have an increased sense of well-being while tending to their pet. The interaction with and love received from a dog can also help people stay positive. Even the mere act of looking at your pet increases the amount of oxytocin, the "feel good" chemical, in the brain.

6. YOU HAVE A MORE ACTIVE SOCIAL LIFE.

Not only does dog ownership indirectly tell others that you're trustworthy, your trusty companion can help facilitate friendships and social networks. A 2015 study published in PLOS One found that dogs can be both the catalyst for sparking new relationships and also the means for keeping social networks thriving. One study even showed that those with dogs also had closer and more supportive relationships with the people in their lives.

7. YOUR DOG MIGHT BE A CANCER DETECTOR.

Your dog could save your life one day: It seems that our canine friends have the ability to smell cancer in the human body. Stories abound of owners whose dogs kept sniffing or licking a mole or lump on their body so they got it checked out, discovering it was cancerous. The anecdotal evidence has been backed up by scientific studies, and some dogs are now trained to detect cancer.

8. YOU'LL BE LESS STRESSED AT WORK.

The benefits of bringing a dog to work are so increasingly obvious that more companies are catching on. Studies show that people who interact with a pet while working have lower stress levels throughout the day, while people who do not bring a pet see their stress levels increase over time. Dogs in the office also lead to people taking more breaks, to play with or walk the dog, which makes them more energized when they return to work. This, in turn, has been shown to lead to much greater productivity and job satisfaction.

9. YOU CAN FIND OUT MORE ABOUT YOUR PERSONALITY.

The kind of dog you have says a lot about your personality. A study in England found a very clear correlation between people's personalities and what type of dogs they owned; for example, people who owned toy dogs tended to be more intelligent, while owners of utility dogs like Dalmatians and bulldogs were the most conscientious. Other studies have found that dog owners in general are more outgoing and friendly than cat owners.

10. YOUR KIDS WILL BE MORE EMPATHETIC.

Though one 2003 study found that there was no link between pet ownership and empathy in a group of children, a 2017 study of 1000 7- to 12-year-olds found that pet attachment of any kind encouraged compassion and positive attitudes toward animals, which promoted better well-being for both the child and the pet. Children with dogs scored the highest for pet attachment, and the study notes that "dogs may help children to regulate their emotions because they can trigger and respond to a child's attachment related behavior." And, of course, only one pet will happily play fetch with a toddler.

The sequel to 2015’s Jurassic World ups the ante with a huge roster of dinosaurs, pterosaurs, and marine reptiles. While some are familiar favorites (see: T. rex), others have never been seen in a major motion picture before. Pull off your nostalgia goggles and let’s take a look at what modern science has to say about the long-gone animals of Jurassic World: Fallen Kingdom.

1. TYRANNOSAURUS

Lived: 68 to 66 million years ago in North America

Diet: Carnivore

Maximum Length: 40 feet

Name Means: “Tyrant lizard”

Apparently, the most popular dinosaur of all time wasn’t above cannibalism: Multiple Tyrannosaurus rex bones have bite marks on them that match the teeth of other tyrannosaurid species. Debate has arisen over the issue of T. rex plumage. University of Alberta paleontologist Scott Persons recently compared tiny skin impressions left behind by Tyrannosaurus and its close cousins Gorgosaurus, Daspletosaurus, and Tarbosaurus. These reveal that the dinos had pebbly scales, but the samples contain no evidence of feathers. Keep in mind though that the skin impressions only represent small patches of the dinosaurs’ tails, necks, abdomens, and pelvises—so Tyrannosaurus might’ve had feathers elsewhere on its body. For the record, Persons thinks the giant carnivore would still look “pretty cool and plenty scary” with a little fuzz. “[Nobody] ever complained that tigers weren’t scary, and they’re fluffy,” he said.

2. APATOSAURUS

Lived: 155 to 150 million years ago in North America

Diet: Herbivore.

Maximum length: 80 feet

Name means: “Deceptive lizard”

In 1879, an unidentified sauropod (a long-necked dinosaur) was found in Wyoming. At first, this creature was given the name Brontosaurus excelsus but in 1903, paleontologist Elmer Riggs rechristened it as Apatosaurus excelsus (the Apatosaurus had been described before the Brontosaurus, so the name had precedence). A few scientists now think the Brontosaurus and Apatosarus actually are distinct and the much better-known name ought to be reinstated for that particular group, but others disagree. Regardless, Apatosaurus was pretty awesome. Some of its bones were pneumatic and the body contained a number of air sacs. Such traits would’ve made the big plant-eater very lightweight for an animal of its size. Apatosaurus may have also been able to break the sound barrier by cracking its sinuous tail like a bullwhip.

3. TRICERATOPS

Lived: 68 to 66 million years ago in North America

Diet: Herbivore

Maximum length: 29 feet

Name means: “Three-horned face”

Give credit where it’s due: Look at the baby Triceratops in Fallen Kingdom and you may notice that the horns above its eyes curve backward ever so slightly. This is scientifically accurate. The brow horns of Triceratops newborns were tiny bumps which bent backward during the adolescent years. Then they changed course and bowed forward while the animals matured. Puncture wounds and lesions on the skulls of adult Triceratops tell us these animals locked horns in head-to-head combat. Triceratops was constantly replacing its teeth, which were arranged in tight clusters and most likely used to shear through fibrous vegetation.

4. SINOCERATOPS

Lived: 75 to 66 million years ago in China

Diet: Herbivore

Maximum length: 19 feet

Name means: “Chinese horned face”

A newcomer to the Jurassic Park films, Sinoceratops first came to light during a 2008 fossil-hunting excursion into China’s Shandong Province. It belongs to the same family as Triceratops and was the first member of this group to be found in Chinese rock. Small, forward-bending horns lined the top of its frill, which was proportionally smaller than that of Triceratops. A single cone-shaped horn sat over the nostrils.

5. ALLOSAURUS

Lived: 155.7 to 150 million years ago in North America and Portugal and possibly elsewhere

Diet: Carnivore

Maximum length: 28 (or possibly 35) feet

Name means: “Different lizard”

In one of the trailers for Fallen Kingdom, a running Allosaurus falls flat on its face. The dinosaur was no stranger to injury in real life. Cracked ribs, broken arms, and badly-infected toes are just a few of the medical maladies that Allosaurus skeletons have been preserved with. Selected as Utah’s official state fossil in 1988, Allosaurus is one of the most commonly found predatory dinos in the American west. Strong neck muscles may have allowed the carnivore to disembowel prey by pulling its head backward in a falcon-esque tugging motion. And here’s something we’d really like to see on the silver screen: According to a 2015 study, Allosaurus could possibly open its jaws at a nightmarish 92-degree angle.

6. MOSASAURUS

Lived: 70 to 66 million years ago in Europe and North America

Diet: Carnivore

Maximum length: 56 feet

Name means: “Lizard of the Meuse River” (It was first discovered along this European river in 1764.)

Mosasaurus wasn’t a dinosaur; it’s more closely related to snakes and monitor lizards than it is to any of the other creatures you’ll read about here. Both Jurassic World flicks show the marine reptile leaping high out of the water to snag unwary prey. According to mosasaur expert Michael J. Everhart though, these animals didn’t have the tail strength or speed to pull off such an athletic feat. Mosasaurus is the most famous member (and the namesake genus) of the mosasaur superfamily. Late in the age of dinosaurs, these were some of the ocean’s major predators. They probably swam like gigantic crocodiles, keeping their flippers pressed against the body. Fossil evidence tells us that mosasaurs gave birth to live young at sea and at least some of them had vertically-fluked tails.

7. PTERANODON

Lived: 88 to 80.5 million years ago in central North America

Diet: Carnivore (probable fishing specialist)

Maximum wingspan: 20 feet (or possibly 24 feet)

Name means: “Toothless wing”

Here’s another non-dinosaur for you. Good old Pteranodon was a kind of North American pterosaur. What’s that, you ask? Pterosaurs were flying reptiles that patrolled the skies from 228 to 66 million years ago. Long before birds or bats took to the air, pterosaurs became the first vertebrate animals to ever achieve powered flight. The good people of Kansas designated Pteranodon itself as one of their official state fossils in 2014. Back in this animal’s heyday, there was a vast inland sea which covered most of the Great Plains, splitting North America in two. Pteranodon may have behaved like a modern albatross, using its narrow wings to soar for vast distances on air currents above the ocean waves. The creatures were apparently keen on seafood: Pteranodon skeletons are sometimes found with masses of fish bones in their throats and stomachs. We may never know how they captured prey, but one idea can be dismissed outright: Not a single known pterosaur had opposable toes, so Pteranodon couldn’t have grabbed things with its feet like the genetically-engineered flyers in Jurassic World do.

8. CARNOTAURUS

Universal Studios and Amblin Entertainment, Inc. and Legendary Pictures Productions, LLC.

Lived: 72 to 69 million years ago in Argentina

Diet: Carnivore

Maximum length: 25 feet

Name means: “Meat-eating bull"

Carnotaurus didn’t show up in the first four Jurassic Park movies, but Michael Crichton wrote the horned creature into his 1995 novel The Lost World. The book depicts Carnotaurus as a nocturnal hunter that can change colors like an overgrown cuttlefish. There’s no reason to put any stock in this idea, but the real Carnotaurus was not without its quirky attributes—including its forelimbs. While T. rex gets a lot of flack for its meager arms, those of Carnotaurus are proportionately smaller, and the Argentine dino didn’t even have any wrist bones. On the flip side, Carnotaurus’s strong legs and powerful tail would’ve made it a gifted sprinter. Skin impressions reveal that its back, neck, and tail were studded with bony knobs, much like the ones Carnotaurus shows off in Fallen Kingdom.

9. GALLIMIMUS

Lived: 70 million years ago in Mongolia

Diet: Probable omnivore

Maximum length: 20 feet

Name means: “Chicken mimic”

Gallimimus belongs to an ostrich-like family of dinosaurs known as the ornithomimids. Though it lacks plumage in the Jurassic movies, real ornithomimids were covered in fuzzy down as youngsters and the adults grew long feathers on their arms. Gallimimus and its brethren couldn’t fly, but their showy, wing-like forelimbs could’ve been used to help them attract mates. Ornithomimids compensated for their lack of teeth by swallowing rocks, which ground up food in the stomach. Exactly what they ate is unclear, though most paleontologists think the ostrich mimics were either omnivorous or herbivorous.

10. BRACHIOSAURUS

Lived: 155 to 140 million years ago in North America

Diet: Herbivore

Maximum length: 72 feet

Name means: “Arm lizard”

Even though it’s poorly represented in the fossil record, Brachiosaurus is well-known to the general public. This is largely due to its breakout role in the first Jurassic Park movie. The Brachiosaurus in that classic film hold their elongated necks in an almost vertical position, and this depiction might not be too far off. A 2010 biomechanical analysis argued that browsing on treetops would’ve been a more energy-efficient option for Brachiosaurus-like sauropods than holding their necks horizontally and eating ground-level plants. It’s interesting to think about the behemoth’s cardiovascular system: In order to pump blood up that lengthy neck and into the head, Brachiosaurus may have required a gigantic heart weighing in the neighborhood of 880 pounds.

11. ANKYLOSAURUS

Lived: 68 to 66 million years ago in North America

Diet: Herbivore

Maximum length: 21 feet

Name means: “Curved lizard”

We know this formidable animal had a backside covered in bony plates; yet because no one’s ever found a complete Ankylosaurus skeleton, scientists disagree about how the armor was arranged. The 19-inch-wide club on its tail was probably a weapon. Using CT scans and anatomical measurements, a Canadian research team estimated that a large Ankylosaurus club could strike its target with enough force to break bones. Evolution made some of the tail vertebrae in these dinosaurs stiff and inflexible so they could support their heavy clubs. A hammer needs its handle after all.

12. STYGIMOLOCH

Lived: 68 to 66 million years ago in North America

Diet: Probable herbivore

Maximum length: 10 feet

Name means: “Styx devil”

It’s kind of ironic that Stygimoloch is mentioned by name in Fallen Kingdom’s promo videos. Paleontologist John R. “Jack” Horner has worked as a consultant for all five Jurassic Park films. He thinks that Stygimoloch is nothing more than the juvenile version of the thick-headed dinosaur Pachycephalosaurus, which lived at the same time and place. (You may remember the latter’s cameo in 1997's The Lost World: Jurassic Park.) This would render the name Stygimoloch invalid. Horner’s argument is supported by the trademark feature of both dinos: the iconic domes on the top of their craniums. Stygimoloch’s skull bones were not fully fused together, suggesting the animal had a lot of growing to do. CT scans have also shown that Stygimoloch’s dome was significantly thinner than that of Pachycephalosaurus. Perhaps these dinos used their special skulls to flank each other—or maybe the thick noggins were designed for heavy-duty headbutts. For his part, Horner has proposed that these were used for identification.

13. STEGOSAURUS

Lived: 155 to 150 million years ago in North America and Portugal

Diet: Herbivore

Maximum length: 23 feet

Name means: “Roof lizard”

Nobody knows what to make of the bony plates on Stegosaurus’s back. If self-defense was their purpose, why do they project upward from the spine, leaving the flanks of this vegetarian wide open? And why do the plates of other spiky-tailed dinosaurs in its family have radically different shapes? One hypothesis is that these bizarre accessories were used to attract mates—much like the peacock’s gaudy tail feathers. Maybe they also helped the small-headed herbivores recognize other members of their own kind from afar. The quartet of spikes on Stegosaurus’s tail were almost certainly used to ward off attackers. Live Stegosaurus got plenty of mileage out of these weapons: One survey, which compared 51 individual spikes, reported that just under 10 percent had been broken and re-healed at the tip.

14. COMPSOGNATHUS

Lived: 150 million years ago in Germany and France

Diet: Carnivore

Maximum length: Four feet

Name means: “Elegant jaw”

Only two skeletons of this dinosaur have ever been discovered, both of which were found with the remains of tiny lizards tucked inside their rib cages. That’s a pretty far cry from the scene in The Lost World: Jurassic Park where a swarm of “Compies” gobble up the man who’s been tormenting them with a cattle prod. But we digress. Named in 1859, Compsognathus used to be the smallest type of non-avian dinosaur known to science. It no longer retains this title, as the creature would’ve dwarfed some more recently-discovered dinos like the 15-inch Mongolian Parvicursor.

Lived: 130-125 million years ago in England, Spain, and Portugal

Diet: Carnivore

Maximum length: 25 feet

Name means: “Heavy claw”

Sail-backed Spinosaurus was the main villain in 2001's Jurassic Park III—a casting choice that irked plenty of fans. Baryonyx was a close relative of this beast who now joins Jurassic World: Fallen Kingdom’s Mesozoic ensemble. Preserved stomach contents have shown that Baryonyx ate fish as well as the herbivorous dinosaur Iguanodon. On each hand, Baryonyx had a 12-inch hooked claw that served an unknown purpose. (Artists like to imagine it as a fishing tool.) The animal’s conical teeth look well-equipped for grabbing hold of slippery prey. Despite the narrowness of its snout, Baryonyx’s jaws were able to withstand a great deal of bending and torsion.

16. VELOCIRAPTOR

Lived: 85 to 70 million years ago in Mongolia and China

Diet: Carnivore

Maximum length: 7 feet

Name means: “Swift thief”

Velociraptor stood less than two feet tall at the hip and weighed around 55 pounds. Michael Crichton’s description of the animal was inspired by its bigger cousin, Deinonychus. Even that dinosaur was smaller than the man-sized predators of Jurassic Park, though. Both Velociraptor and Deinonychus were dromaeosaurs: bird-like carnivores with bony rods in their tails and sickle-shaped toe claws. (When we say “bird-like,” we mean it: Dromaeosaurs are thought to be some of our feathered friends’ closest relatives. Many had plumage; Velociraptor itself came with sizable feathers on each arm.)

The notion that they hunted in packs can be traced back to the maverick paleontologist John Ostrom of Yale. During the 1960s, he worked at a Montana dig site where four Deinonychus were found around the body of a larger herbivore named Tenontosaurus. Ostrom’s belief that dromaeosaurs hunted in organized groups gained traction with scientists and novelists alike. A newer interpretation of the data is that the dinos lived alone and at most occasionally came together to mob vulnerable plant-eaters.
