There's a gooey time capsule in the heart of Los Angeles, left over from an era when saber-toothed cats, dire wolves, camels, and giant sloths prowled southern California. At the site known today as the La Brea Tar Pits and Museum, natural asphalt has bubbled up from below the ground's surface since the last Ice Age. This murky sludge has trapped and made fossils out of thousands of creatures, as small as bees and as big as mammoths. Here are a few of the amazing discoveries made there.

1. MORE THAN 3.5 MILLION FOSSILS HAVE BEEN DISCOVERED.

The tar pits have yielded one of the biggest collections of Ice Age fossils in the world, and collectively, the statistics are stunning. More than 600 species have been found, from snakes and mollusks to sloths and mountain lions. Of the mammals found at La Brea, around 90 percent are carnivores. (Amazingly, the pits have yielded more 200,000 individual dire wolf specimens alone.) The common explanation is that when big herbivores like mammoths got stuck in the asphalt, they would have looked like an easy meal to predators—who would then become stuck in the tar themselves.

2. PALEONTOLOGISTS STILL DIG THERE 361 DAYS A YEAR.

Why 361? The site is closed July 4, Thanksgiving, Christmas, and New Year's Day. The rest of the time, science is happening. The first excavations at the tar pits began in the early 20th century, and if you visit today, you're still likely to see scientists preserving bones or digging in the asphalt. Still, people often don't realize that it's a place for active scientific research, as the tar pits lie in the middle of Los Angeles, a city synonymous with the entertainment industry. Emily Lindsey, assistant curator at the La Brea Tar Pits and Museum, tells Mental Floss that this has led to some confusion on the part of visitors, who "think sometimes the excavators are actors, or part of an art exhibit, or robots."

3. THE ONLY DINOSAURS FOUND THERE ARE BIRDS.

After the paleontologists at La Brea have convinced you they aren't robots, they'll be quick to clear up another misconception: They don't dig up dinosaurs. (Although, technically, they do. "We have 163 species of birds," Lindsey says. Yes, birds are dinosaurs.) Most of the fossils at La Brea date from 11,000 to 50,000 years ago—about 65 million years after dinosaurs went extinct.

4. THE PRESERVATION OF FOSSILS IS EXCEPTIONAL.

Sticky asphalt is a pain to clean off the bones, but it also keeps them in pristine condition. This means scientists can look at features as subtle as the markings on carnivore teeth. One study in 2014 looked at microscopic patterns on the teeth of five species of big cats found at La Brea. The researchers concluded that the mountain lion was the only one to survive into the present because it wasn't a picky eater, and could survive changes in its food supply.

5. IT'S SO GOOD THAT THE PITS PRESERVE ENTIRE ECOSYSTEMS.

The big, extinct megafauna might soak up all the attention at La Brea, but paleontologists at the site have also recovered paper-thin fossils of pollen, bees, plant matter, insects, and other tiny organisms. "This is such a unique site because it's one of the only paleontological sites in the world where you can get an entire ecosystem represented," Lindsey says. "The big animals have pretty broad climate tolerances. Something like an insect has a much more narrow range."

This is important because the presence of smaller organisms can relay more specific information about the ecosystem. And because La Brea has such a long record of fossils, scientists can track how those ecosystems changed—or didn't—over time. For instance, one recent study of beetle fossils in the tar pits suggests that the climate of southern California has been relatively stable over the past 50,000 years. Yes, L.A. has had great weather for a very long time.

6. THE TAR PITS ARE DEATH TRAPS—AND YET ALSO SUPPORT LIFE.

A decade ago, scientists discovered about 200 species of microorganisms living in the asphalt with no water, little to no oxygen, and a heavy dose of toxic chemicals. Some of these microbes represented families of bacterial species that had never been seen before. By studying extremophiles thriving in such hostile environments, scientists may learn more about how life might exist on other planets.

7. ONLY ONE HUMAN SKELETON HAS BEEN FOUND THERE.

In 1914, researchers at the tar pits discovered a 9000-year-old set of human remains of a 20-something-year-old female, dubbed "La Brea Woman." Though some had speculated that she had been trapped in the asphalt or that she was Los Angeles's first homicide case, later studies suggested La Brea woman's remains had been ceremonially reburied in the asphalt, possibly with a domestic dog at her side. No other human remains have been found at La Brea. Historical accounts suggest that local tribes like the Chumash and Tongva used the asphalt from the tar pits as a glue or caulk for their wooden boats, so they must've tread carefully around the tar pits. But most of the fossils from the tar pits date from the period before humans populated the region. Lindsey says a new project will look at what was happening at the tar pits during the Holocene—the period that started after the end of the last Ice Age—which could reveal how the arrival of humans might have contributed to the extinction of big mammals.

8. A POLICE DIVER WORKING A MURDER CASE SURVIVED A PLUNGE INTO A PIT.

In 2013, a police diver willingly went 17 feet under the surface of the sludge to hunt for weapons in a cold case homicide investigation. "I've been under moving ships, in underwater reservoir sheds," LAPD Sergeant David Mascarenas told the Los Angeles Times. "This is by far the craziest thing I've ever done." Despite the bad visibility, Mascarenas was apparently able to make out underwater pinnacles of tar, and he did recover multiple items of interest. He probably also succeeded in sending the LAPD's message that they would "go as far as we can to make it as difficult for a suspect to discard evidence."

9. THERE ARE MORE PITS OUT THERE.

"There's a couple of sites that have barely been studied but would probably be as rich as the La Brea tar pits," Lindsey says. Venezuela has several tar pits, for instance, but because of the political situation, they haven't been as intensely studied.

10. THE NAME IS REDUNDANT.

"La Brea" in Spanish means "the tar." So when you say "the La Brea tar pits," you're really saying "The the tar tar pits." It's on the long list of tautological place names that also includes Lake Tahoe and the Sahara Desert.

12 Doomed Facts About the S.S. Edmund Fitzgerald

The wind in the wires made a tattle-tale sound
When the wave broke over the railing
And every man knew, as the captain did too
'Twas the witch of November come stealin'
-Gordon Lightfoot, "The Wreck of the Edmund Fitzgerald" (1976) 

On November 10, 1975, two ships made their way in tandem across the stormy waters of Lake Superior. One was the Arthur M. Anderson, led by Captain Jesse Cooper. The other, captained by Ernest McSorley, was the S.S. Edmund Fitzgerald.

The ship was last seen on radar around 7:15 p.m. All 29 men on board were lost with it, and today, more than four decades after the most famous shipwreck in Great Lakes history, the cause is still a mystery.

Here's what we do know about the S.S. Edmund Fitzgerald, and what happened to it that fateful day:

1. IT WAS THE LARGEST SHIP ON THE GREAT LAKES.

The large cargo vessels that roamed the five Great Lakes were known as lakers, and the S.S. Edmund Fitzgerald was, at the time, the biggest ever built. It was constructed as a “maximum sized” bulk carrier and spanned 729 feet—the first laker to reach that length—sat 39 feet high with a width of 75 feet, and weighed more than 13,000 tons without cargo. It was christened on June 8, 1958, and made its first voyage on September 24 the same year. 

2. THE SHIP WAS OWNED BY AN INSURANCE COMPANY.

Great Lakes Engineering Works of Ecorse, Michigan, was contracted to build the ship in 1957 by Northwestern Mutual Insurance Company, which had invested heavily in the iron and minerals industries. With the commissioning of the Fitzgerald, Northwestern Mutual became the first American insurance company to build its own ship—at a cost of $8.4 million, the most expensive price tag for a freighter at the time, according to Michael Schumacher’s The Mighty Fitz.

3. IT WAS NAMED AFTER THE HEAD OF THE COMPANY.

The chairman of Northwestern Mutual had a long history with the Great Lakes shipping industry. Edmund Fitzgerald’s grandfather captained a ship on the lakes, his father owned a shipyard, and they both had ships named after them. After construction of the Fitzgerald was complete, Northwestern Mutual placed its charter with the Columbia Transportation Division of Oglebay Norton Company, based in Cleveland. 

4. THE SHIP'S MAIN JOB WAS HAULING IRON ORE.

Most lakers traversing the Great Lakes and the connecting waterways carry massive amounts of raw materials such as rock, salt, and grain. The Edmund Fitzgerald generally loaded taconite, low-grade iron ore, from mines on the shores of Minnesota and transported the pellets to steel mills near Detroit and Toledo, Ohio.

5. "THE FITZ" WAS WELL-KNOWN EVEN BEFORE IT SANK.

Its impressive size made the ship popular with boat-watchers, and over the years it garnered many nicknames, including “The Queen of the Great Lakes,” “The Toledo Express,” and the unfortunate “Titanic of the Great Lakes.” Crowds would watch as the massive freighter moved through the locks at Sault Ste. Marie in Michigan’s Upper Peninsula. The “Soo” Locks, which connect Lake Superior to Lake Huron, allowed the Fitz to reach ports on the lower Great Lakes.

6. THE SHIP RAN INTO A DEADLY STORM ON LAKE SUPERIOR.

November is a brutal month on the Great Lakes. Frequent storms and hurricane-force winds can batter even the toughest-built freighters. On November 9, the Fitz was loaded with 26,116 tons of iron ore pellets at the Burlington Northern Railroad Dock in Superior, Wisconsin. It left at 2:30 p.m. A second ship, the Arthur M. Anderson, sailed 10-15 miles behind the Fitzgerald as a precaution, and the two ships remained in radio contact until just after 7 p.m. on November 10.

Gale warnings had been issued by the National Weather Service the previous day, and by the morning of the 10th, the advisories had been upgraded to an official storm warning. 

As swells reached 35 feet and winds raged at nearly 100 mph, the ship contacted Coast Guard officials in Sault Ste. Marie and said they were taking on water. Later, a blizzard obscured the Fitz on the Anderson’s radar, but Captain Ernest McSorley, who was on his final voyage before retirement, assured a crew member on the Anderson at 7:10 p.m. that, “We are holding our own.” It was the last anyone heard from McSorley or the Fitzgerald.

7. NO DISTRESS SIGNAL WAS SENT.

After that, there was nothing on the radar. No radio contact. The ship was approximately 15 miles north of Whitefish Point when it seemingly vanished. Captain Cooper, on the Anderson, was in contact with the Coast Guard and made it to Whitefish Point sometime after 8 p.m. with no sign or word from the Fitzgerald. Later, the Anderson made its way back into the storm to search for the ship, but found only a pair of lifeboats and debris. 

8. ALL 29 CREW MEMBERS DIED. 

Along with the captain, the other crew members of the Fitzgerald included porters, oilers, engineers, maintenance workers, cooks, watchmen, deck hands, and wheelsmen. Most crew members were from Wisconsin, Michigan, Ohio, and Minnesota.

9. THERE IS STILL NO DEFINITIVE EXPLANATION FOR THE SINKING.

The treacherous weather conditions are an obvious factor, but experts differ on what they think specifically caused the accident. Following the wreck, the U.S. Coast Guard and National Transportation Safety Board agreed that the tragedy was likely due to faulty cargo hatches, which led to flooding. Predictably, there are still those who harbor other theories, including unsecured hatches, maintenance troubles, massive waves, structural issues, and yes, even aliens. Author and Great Lakes historian Frederick Stonehouse posited that the ship likely hit a shoal and took on too much water before plunging into Lake Superior.

10. THE TRAGEDY WAS IMMORTALIZED BY A CANADIAN FOLK SINGER.

Gordon Lightfoot, who had released 10 albums from 1966 to 1975, was inspired to write the ballad “The Wreck of the Edmund Fitzgerald” after reading an article about the tragedy in Newsweek. He included the song on his 1976 album Summertime Dream, and the nearly six-minute single reached #2 on the Billboard Hot 100 charts that year and became Lightfoot’s second-most successful hit.

11. FAMILY MEMBERS REQUESTED A SYMBOLIC MEMORIAL FROM THE SHIP.

The U.S. Navy and Coast Guard deployed planes and cutters with magnetic anomaly detectors, sidescan sonar, and sonar survey to find the wreckage. In May, a Navy underwater recovery vehicle was sent to the site, and on May 20, 1976, the ship was spotted 535 below the surface of the lake.

In the decades since, only a handful of people have been able to see the wreck, which lies in two pieces. A pair of divers made their way down in 1995, the same year a crew—with help from the Canadian Navy, the National Geographic Society, Sony, and the Sault Ste. Marie Tribe of Chippewa Indians—retrieved the ship's bell at the behest of the families of those who were lost. The Canadian government has since prohibited access to the site. 

In eerie archival tapes below, you can hear Anderson skipper Jesse Cooper correspond with the Coast Guard, and see video of the wreck.

12. THERE'S AN ANNUAL REMEMBRANCE DAY.

The annual Edmund Fitzgerald memorial ceremony takes place on November 10th at the Great Lakes Shipwreck Museum at Whitefish Point. The recovered and restored bell will toll 29 times for each member of the Fitzgerald's crew, and a 30th for the estimated 30,000 mariners lost on the Great Lakes.

Wreckage of a World War II Nazi 'Flying Bomb' Found in English Forest

A detonated German V-1 flying bomb from World War II has been uncovered by archaeologists in the English countryside, Live Science reports. Also known as a “doodlebug,” this particular unmanned cruise missile was likely bound for London when it was launched in 1944. Instead, it was shot down over the Packing Wood forest in Kent, England, where it laid for more than 70 years.

The flying bomb was found last month by Research Resource, a private archaeological group run by brothers Colin and Sean Welch. Their research revealed that the V-1 was brought down by a Polish pilot on August 6, 1944.

"Kent was never a target, and the V-1s that fell were either brought down by fighter aircraft, anti-aircraft gunfire, the balloon barrage, or malfunction of the device,” Colin Welch told Kent Online. "This site at Packing Wood is remarkable as it appears that the missile crashed pretty cleanly in that its remains are within the center of the crater.”

Nearly 10,000 V-1 bombs were directed at targets in southeast England between 1944 and 1945, according to Colin Welch. Many were launched from German-occupied Holland.

These 1700-pound missiles were considered “retaliation weapons” and were ordered by Hitler in response to Allied bombings of German cities in 1943. V-1s were responsible for more than 6000 deaths in Britain—not to mention a great deal of destruction. One of these bombs obliterated George Orwell’s home in London in 1944 and nearly destroyed his manuscript of Animal Farm.

The Welch brothers have conducted several war-related projects in the Kent region, including a three-year excavation of the site where a V-2 rocket crashed. The brothers want to create an online museum to showcase 3D renderings of the weapons they’ve found.

"This is our history, and it's got to be documented somehow in a responsible way," Welch told Live Science.
