Sillhouette of Megapiranha in black compared to today's piranha
|Scientific Name||Megapiranha paranensis|
|Lived||8-10 million years ago|
Assuming that Megapiranha had a body proportionally similar to that of modern piranhas, it measured a meter in length, which is much larger than today's species. Only some premaxillae and teeth of the genus have been found.
Megapiranha was first discovered in the early 1900s, but the fossils were not described until 2009 in a paper by Alberto Luis Cione and colleagues.
PaleobiologyEditThe teeth of Megapiranha are similar to both modern piranhas (which are carnivorous) and pacu (which are herbivorous). It is possible, therefore, that Megapiranha may have been omnivorous.
