An article published in the journal “Current Biology” describes the discovery of a bony fish that lived about 150 million years ago. Named Piranhamesodon pinnatomus, it’s part of the collection of the Jura-Museum in Eichstätt and was discovered in the same limestone deposits in which Archeopteryx fossils were found, in southern Germany. The fossils discovered show that the this fish teeth were similar to those of modern piranhas and it probably used them in the same way.
