The fossil of a piranha-like jurassic fish shows a flesh-slicing eating ability. The specimen was the first bony fish to have this capacity. Teeth were much like the South American piranha. However, the ancient creature lived in the ocean not in freshwater. People eat the piranha and say it tastes like other fish.
