Researchers Uncover What's Believed to Be the Oldest Shipwreck in Lake Erie

In the fall of 1829, a ship had departed from Put-in-Bay, Ohio, but failed to reach its final destination. Now, researchers believe they have finally found its remains, which would make it the oldest shipwreck ever recorded in Lake Erie, if their theory is confirmed.

Remote sensors detected the wreckage three years ago, and the National Museum of the Great Lakes in Toledo, Ohio, has been working to identify the ship ever since then, according to The Blade newspaper in Toledo. Experts believe they have narrowed down their search from 200 possible shipwrecks to three. The museum is now raising money via Indiegogo to fund an underwater survey and partial excavation of the ship.

Strong evidence suggests that the wreckage belongs to one particular schooner—a sailing vessel with at least two masts—that was built in Cleveland in 1821. It was named the Lake Serpent in reference to a carving of a sea serpent on its bowsprit, according to the museum. In the fall of 1829, it left from Put-in-Bay on South Bass Island in Lake Erie, where crews loaded limestone onto the ship. It's unknown what happened after that, but we do know that the ship never reached its final destination. Local newspapers reported that the bodies of the captain and other crew members washed ashore in Lorain County, located about 25 miles from Cleveland, the ship’s intended destination.

It’s a wonder that the shipwreck was even detected at all. Tom Kowalczk, director of remote sensing for the Cleveland Underwater Explorers, which has a partnership with the Toledo museum, nearly wrote off the wreckage as a “small, barely noticeable anomaly” when he first detected it in 2015.

“The target was so small it was almost dismissed as a natural artifact,” Kowalczk wrote in a discovery report. “We were looking for shipwrecks! Curiosity got the upper hand and the boat was turned for a second look.”

Museum officials hope this finding will reveal unknown details about the design of early 19th-century ships from that region. Shipwreck hunters continue their search for another schooner called Lexington, which sank in the 1840s.

After 110 Million Years, This Spider Fossil's Eyes Are All Aglow

A big, hairy spider is enough to give anyone a fright. So you can imagine what a set of eight glowing eyes attached to a body like that might do to an arachnophobe's psyche. One such spider was discovered recently by researchers, but don’t worry—the iridescent-eyed arachnid has been dead for 110 million years.

As Popular Science reports, this rare, fossilized specimen was found in South Korea’s Lower Cretaceous Jinju Formation. The find was unusual for a couple of reasons. For one, spiders are not usually preserved in rock because the soft-bodied creatures decay easily. It’s also not every day that you see a long-dead spider with glowing eyes. On top of that, researchers found two well-preserved examples of these spiders, which were described in a recent issue of the Journal of Systematic Palaeontology.

Both specimens belong to Lagonomegopidae, an extinct family that predated jumping spiders. The glow is caused by a layer of tissue called tapetum lucidum, which coats the spider’s eyes and reflects light, allowing the spider to hunt at night with ease. Many animals have it—including cats, dogs, horses, deer, raccoons, and some modern spiders—but this is the first paper to describe its existence in a fossilized spider. The tapetum is crescent-shaped and “looks a bit like a Canadian canoe,” according to Paul Selden, a geology professor at the University of Kansas and co-author of the paper.

“Because these spiders were preserved in strange silvery flecks on dark rock, what was immediately obvious was their rather large eyes brightly marked with crescentic features,” Selden said in a statement.

Researchers now want to go back and take another look at similar spiders preserved in amber, which are far more common than spiders fossilized in rock. The challenge is determining whether those specimens also have a layer of tapetum lucidum coating their eyes.

“Amber fossils are beautiful, they look wonderful, but they preserve things in a different way,” Selden said. “Now, we want to go back and look at the amber fossils and see if we can find the tapetum, which stares out at you from rock fossils but isn’t so obvious in amber ones because the mode of preservation is so different.”

A (Still-Sharp) Medieval Sword Was Pulled from a Sewer in Denmark

If the legend of King Arthur and Excalibur is anything to go by, anyone who successfully extracts a sword in a stone will be treated like royalty. The fable doesn’t say anything about the reward one gets for removing a medieval weapon from feces, though.

As Smithsonian reports, a pipe layer and an engineer recently found a sword from the medieval era while doing construction work on a sewer in Aalborg, Denmark’s fourth-largest city. The relic was plucked from a layer of waste that had accumulated atop an old slab of pavement that once ran through the city.

Most remarkably, the sword was still intact—and the blade still sharp. It’s about 3.5 feet long and of extremely high quality, according to archaeologists. The sword may have been used between 1100 and 1400, but the likeliest explanation is that it got separated from its owner sometime in the 14th century. “Findings from here have always pointed to the 1300s, so the sword must have ended up in the earth in this century,” archaeologist Kenneth Nielsen said in a translated statement.

It’s rare for such an important historical artifact to turn up in such an unlikely—and unhygienic—place. Swords were valuable and highly prized possessions, and they were treated as such. They were typically buried with their owners, but no graves are situated above the sewer where the weapon was found.

The country’s history offers some clues about what may have transpired, though. In the 1300s, power struggles and internecine war were common throughout Denmark. “The best explanation we can come up with is that the owner of the sword was defeated in a battle,” Nielsen told The Local Denmark. “In the tumult, it was then trod down into the layer of mud that formed the street back then.”

Similarly, a 14th-century sword was found in a Polish peat bog in 2017, and archaeologists suspect the owner either sunk into the marsh and met a grisly end, or merely dropped his weapon and was unable to retrieve it.

While these questions will likely remain unanswered, members of the public will have the chance to admire the Danish "sewer sword" in all its glory at the Aalborg Historiske Museum (Aalborg Historical Museum), which is located near the site where the sword was found. Fortunately for future visitors, it will be cleaned and preserved first.
