150-million-year old, piranha-like specimen is earliest known flesh-eating fish

Researchers have described a remarkable new species of fish that lived in the sea about 150 million years ago in the time of the dinosaurs. The new species of bony fish had teeth like a piranha, which the researchers suggest they used as piranhas do: to bite off chunks of flesh from other fish. https://www.sciencedaily.com/releases/2018/10/181018141129.htm
