A Piranha-like Pycnodontiform Fish from the Late Jurassic (Current Biology)

Kölbl-Ebert et al. describe a new pycnodontiform fish, Piranhamesodon pinnatomus, from the Jurassic. It has specialized morphological features for cutting flesh, including piranha-like teeth. As a marine fish contemporary with dinosaurs, it is the oldest known flesh-eating ray-finned fish, exhibiting remarkable convergent evolution with piranhas.
