A fossil from a late-Jurassic piranha-like fish was unearthed by scientists in southern Germany, according to Australian news agency ABC. Even more remarkable than the age of the fossil – 150 million years old – is the fact that the limestone deposit also contains some of the fish's sacrifices.
Fish with chunks missing from their fins were found near the predatory fish. Piranhamesodon pinnatomus . But apart from the razor-sharp teeth of the predator, it does not look like your usual meat-eating fish. It belonged to an extinct order of bony fish that lived in the time of the dinosaurs, and so far scientists did not know that there was a species of bony fish that tore themselves into their prey. This makes it the first carnivorous bony fish, long before the piranha.
"Fish as we know them, bony fish, did not bite meat from other fish at that time," Dr. Martina Kölbl-Ebert, the paleontologist, who found the fish together with her husband Martin Ebert. "Sharks were able to bite out chunks of meat, but in the course of history, bony fish have either fed invertebrates or swallowed their prey whole ̵
Kölbl-Ebert, the director of the Jura Museum in Eichstätt, says she was stunned to see the sharp teeth of bony fish sheep with a growl like a wolf. "This clever disguise made the fish a terrible predator, and scientists believe the fish has used" aggressive mimicry "to invade unsuspecting fish.
The fossil was discovered in southern Germany in 2016 Journal Current Biology found in a quarry in which other fossils such as the Archeopteryx dinosaur were found in the past.  [h/t the ABC]
