Scientists Find Fossil of 150-Million-Year-Old Flesh-Eating Fish—Plus a Few of Its Prey

A fossil of an unusual piranha-like fish from the Late Jurassic period has been unearthed by scientists in southern Germany, Australian news outlet the ABC reports. Even more remarkable than the fossil’s age—150 million years old—is the fact that the limestone deposit also contains some of the fish’s victims.

Fish with chunks missing from their fins were found near the predator fish, which has been named Piranhamesodon pinnatomus. Aside from the predator’s razor-sharp teeth, though, it doesn’t look like your usual flesh-eating fish. It belonged to an extinct order of bony fish that lived at the time of the dinosaurs, and until now, scientists didn’t realize there was a species of bony fish that tore into its prey in such a way. This makes it the first flesh-eating bony fish on record, long predating the piranha. 

“Fish as we know them, bony fishes, just did not bite flesh of other fishes at that time,” Dr. Martina Kölbl-Ebert, the paleontologist who found the fish with her husband, Martin Ebert, said in a statement. “Sharks have been able to bite out chunks of flesh, but throughout history bony fishes have either fed on invertebrates or largely swallowed their prey whole. Biting chunks of flesh or fins was something that came much later."

Kölbl-Ebert, the director of the Jura Museum in Eichstätt, Germany, says she was stunned to see the bony fish’s sharp teeth, comparing it to “finding a sheep with a snarl like a wolf.” This cunning disguise made the fish a fearful predator, and scientists believe the fish may have “exploited aggressive mimicry” to ambush unsuspecting fish.

The fossil was discovered in 2016 in southern Germany, but the find has only recently been described in the journal Current Biology. It was found at a quarry where other fossils, like those of the Archaeopteryx dinosaur, have been unearthed in the past.

Stonehenge Builders Likely Descended From Immigrants, Genetic Analysis Says

There's a lot we don't know about Stonehenge, but until recently, the structure was thought to have been built by hunter-gatherers native to what's considered England today. A new study disputes that theory. As IFL Science reports, Stonehenge was likely the the work of Turkish people who migrated to Britain 6000 years ago and their descendants.

In the new report published in the journal Nature: Ecology & Evolution, scientists from London's Natural History Museum and University College London explain how they analyzed the DNA from the remains of dozens of people who lived in Britain between 8500 BCE and 2500 BCE.

The results contained fewer native British genes than expected: Researchers found that when the people whose bones they studied were alive, most of Britain's hunter-gatherer population had already been replaced by farmers from the Aegean region.

Roughly 6000 years ago, people from what is now Turkey traveled across Europe and settled in Britain. In addition to reshaping the British gene pool, the new group also introduced agriculture to the area. Archaeologists have long debated whether farming is something that was brought to Britain by a different culture or if native hunter-gatherers gradually adopted it on their own.

"The transition to farming marks one of the most important technological innovations in human evolution. It first appeared in Britain around 6000 years ago; prior to that people survived by hunting, fishing and gathering," study co-author Mark Thomas said in a press release. "Our study strongly supports the view that immigrant farmers introduced agriculture into Britain and largely replaced the indigenous hunter-gatherer populations."

That means Stonehenge, the first part of which was constructed around 3000 BCE, was likely the work of people who were culturally and genetically closer to ancient Aegeans than native Britons. But how they moved the 25-ton stones to their current location and for what purpose remains a mystery.

An Ancient Shipwreck Has Been Turned Into an Underwater Museum Off the Coast of Greece

If you love ancient history and eerie, abandoned places, it might be time to break out the scuba diving gear and book a flight to Greece. As AFAR reports, the site of an ancient shipwreck near Alonissos, a Greek island in the Aegean Sea, has been turned into an underwater museum.

While underwater museums exist in Florida, Mexico, and Europe, those destinations are geared more toward art and sculpture lovers. In this case, divers will be swimming alongside a piece of history dating back to the late 5th century B.C.E. The wooden cargo ship, which sank for an unknown reason, disintegrated long ago. However, the seabed is still covered in thousands of amphoras (a kind of storage jar used in ancient Greece and Italy), which likely held wine.

Dubbed the Peristera shipwreck, the site was discovered in the early 1990s. It was named after the uninhabited island where it was discovered, but guided dives of the site leave from the harbor of Steni Valla on Alonissos, which is located in the Northern Sporades group of islands in the northwest Aegean Sea.

Peristera is the first shipwreck in Greece to be made accessible to the public, but it won’t be the last. As part of a program funded by the European Commission, the country also plans to open up three other shipwreck sites in the Pagasetic Gulf. The efforts are part of a push to promote eco-friendly tourism while also highlighting the country’s rich history.

“The goal is in the next two years to make the country’s shipwrecks visitable, but also to provide important information and raise awareness about underwater monuments, such as the Peristera wreck off Alonissos,” alternate culture minister Kostas Stratis said at an event, according to the Greek City Times.

Italy and Croatia are also expected to create their own underwater museums in the future via the same program, called BlueMed.
