Megapiranha

Megapiranha is a genus of piranha from the Miocene of Argentina.

Description
Megapiranha has a body proportionally similar to that of modern piranhas, it measures a meter in length, which is much larger than today's species. Only some premaxillae and teeth of the genus have been found.

Discovery
Megapiranha was first discovered in the early 1900s, by Alberto Luis Cione and colleagues. This information is incorrect.

Paleobiology

 * 1) The teeth of Megapiranha are similar to both modern piranhas (which are carnivorous) and pacu (which are herbivorous). It is possible, therefore, that Megapiranha may be omnivorous.
