10 Things You Might Not Know About Diplodocus

Sabreguy29

Diplodocus ranks among the most impressive animals that’s ever walked the earth and, thanks to a great philanthropist, it’s also become one of the world’s favorite dinosaurs. So, let’s get a little better acquainted with this captivating creature.

1. Andrew Carnegie Was a Big Diplodocus Fan.

A steel industry giant who loved his dinos, Carnegie financed several fossil-finding expeditions, one of which yielded a gigantic Diplodocus specimen in 1899. As an act of goodwill, he donated meticulously-crafted casts of the skeleton (nicknamed “Dippy”) to museums in such cities as Paris, Berlin, Mexico City, Moscow, and London.

2. Young Diplodocus Were Finicky Eaters.

Like many human kids, adolescent Diplodocus were a bit picky. Because they had much narrower snouts than adults did, juveniles proportionally grabbed less food with each bite. It’s been suggested that this is because they exclusively ate higher-quality plants while growing up.

3. A Faction of Paleontologists Once Thought that Diplodocus Sprawled Like a Lizard.

We now know that Diplodocus held those column-like legs directly underneath its body. Back in 1910, however, some scientists claimed that these limbs actually jetted out to the side. Enter William Jacob Holland (1848-1932), a zoologist and minister with a knack for cheesy one-liners. As Holland pointed out, this king-sized dinosaur had a deep, protruding rib cage. Ergo, if Diplodocus sprawled, its dragging belly would’ve carved a huge trench—or “rut”—through the soil every time it went for a stroll. Dripping with sarcasm, he added “This might perhaps account for his early extinction. It is physically and mentally bad to ‘get into a rut.’”

4. One Particularly Huge Diplodocus Species Was Over 100 Feet Long.

Conservative estimates hold that Diplodocus hallorum—previously known as Seismosaurus halli stretched a remarkable 110 feet from end to end. So, does this make it the longest dinosaur ever? No. Patagonia’s Argentinosaurus, India’s Bruhathkayosaurus, and Colorado’s Supersaurus appear to have been comparable in length. And then there’s the mysterious Amphicoelias, which quite possibly dwarfed them all. But because all five are only known from annoyingly-incomplete specimens, paleontologists can merely speculate about which one (if any) deserves that crown.

5. It Had Plenty of Long-Necked Neighbors.

Unless you’re living in a Land Before Time movie, “sauropod” is the proper term for “long-necked” herbivorous dinosaurs. One hundred and fifty million years ago, Diplodocus lived alongside several other members of this group in the wilds of North America, including Camarasaurus, Brachiosaurus, and even Apatosaurus, the dino formerly known as Brontosaurus.

6. Some Believe Diplodocus’ Whip-Like Tail Could’ve Broken the Sound Barrier.

These herbivores might have used their sinuous tails to produce an intimidating thwacking noise in the event of a predator attack. Hopefully, that’d be frightening enough; being forced to actually make contact with the opponent’s skin likely meant breaking several of its own vertebrae.

7. Diplodocus Didn’t Chew—It Gulped.

When you’ve got a 12-ton body to feed, chewing is a time-waster you can’t afford. According to a 2012 skull analysis, Diplodocus’ jaws were designed to remove leaves from branches by stripping and/or plucking them off. Whatever Diplodocus consumed was mostly swallowed whole before getting broken down during digestion. 

8. Scientists Aren’t Sure if Diplodocus Held its Head High.

Would sauropods like Diplodocus have preferred holding their necks horizontally (as seen above) or raising them upwards? A case can be made for both interpretations. On the one hand, if such a large neck was kept parallel to the ground, blood might’ve flowed more easily to the dino’s brain. Yet, on the other hand, this could prevent Diplodocus from browsing on tree limbs, cutting off a potentially important food source. Also, living animals almost universally incline their necks upwards to some degree.

9. Diplodocus Replaced its Teeth With Incredible Speed.

Like today’s sharks, this animal and its kin constantly replaced their own teeth and “would’ve had a fresh tooth in each position every one to two months, sometimes less,” says Dr. Michael D’Emic of Stony Brook University. “Effectively, sauropods took a ‘quantity over quality’ approach” to their dental arsenals.

10. Teddy Roosevelt Wrote That If Diplodocus Were Still Alive, He’d Enjoy Shooting One.

When you’re hunting dinosaurs, carrying a big stick doesn’t cut it. In 1905, Carnegie and Holland visited the U.K. to show off one of their Diplodocus casts, to the delight of British cartoonists. After they returned home, the Bull Moose himself wrote an enthusiastic letter of congratulations: “What a bully time you must have had in London! The delight which the political caricaturists made of your Diplodocus was most amusing. What a pity the thing died out! What glorious shooting we would have had on the Little Missouri if it survived to our time!”

New LEGO Set Recreates Jurassic Park's Iconic Velociraptor Chase Scenes

Jurassic World: Fallen Kingdom, the fifth installment in the Jurassic Park franchise, is skulking into theaters on June 22. That makes now the perfect time to revisit the original film in LEGO form.

This LEGO set, spotted by Nerdist, depicts some of the most suspenseful scenes from the 1993 movie. There's the main computer room where Ariana Richards's Lex shows off her hacker skills while Alan Grant (Sam Neill) and Ellie Sattler (Laura Dern) struggle to keep a hungry dinosaur from barging in. Just like in the film, the door features a deadbolt lock that's velociraptor-proof (though, unfortunately for the characters, the detachable window is not). Other Easter eggs hidden in this part include a map of Isla Nublar and a screener saver of LEGO Dennis Nedry (Wayne Knight).

In the neighboring room, you'll find the cold storage unit where the dinosaur embryos are kept, along with the fake shaving cream can Nedry uses to steal them. The final section is the kitchen, where Tim (Joseph Mazzello) and Lex are stalked by the velociraptor. There's less room for them to hide in the LEGO version compared to the movie set, but there is at least one functioning cabinet for Lex to tuck herself into. Closer inspection reveals even more details from the film, like the lime-green Jello Lex is eating when the raptors first arrive and the step ladder the gang uses to escape into the air ducts during the final chase.

WHY? is our attempt to answer all the questions every little kid asks. Do you have a question? Send it to why@mentalfloss.com.

Actually, there are still dinosaurs: Birds! But let’s talk about that a little later. Scientists have found clues in rocks and fossils that tell us that by 65 million years ago, the climate (CLY-met), or usual weather, of the Earth had changed a lot, becoming cooler and drier. That was hard on the heat-loving dinosaurs. But that’s not why almost all of the dinosaurs became extinct, or disappeared forever. Scientists think a terrible event occurred that killed them off.

In 1991, scientists discovered a huge 110-mile-long crater, or hole, in the Gulf of Mexico. They think this crater was made by a giant, fiery, 6-mile-wide asteroid (AST-er-oyd) from space that smashed into the Earth about 65 million years ago. The impact was more powerful than any bomb we have ever known. Scientists believe this event killed most plant and animal life—including the dinosaurs. The asteroid probably caused shockwaves, earthquakes, fireballs, wildfires, and tidal, or really big, waves. It also sent huge amounts of dust and gas into the atmosphere, which is like a big blanket of air that surrounds the Earth. That was really bad for the planet.

The dust blocked sunlight, making the planet very cold and dark. Then, over time, the gases trapped heat, causing the Earth to get even hotter than it was before the asteroid hit. This change was deadly for most dinosaurs, and they became extinct. But birds survived. Many millions of years earlier, they had evolved (ee-VOL-ved), or changed slowly over time, from one group of dinosaurs. And when the dinosaurs disappeared, mammals diversified (die-VERSE-uh-fide), or changed, into many different kinds of animals—including us, many millions of years later. So the next time you see a bird swoop by, wave hello to the little flying dinosaur!
