Difference between Megafauna and Reptile

Megafauna vs. Reptile

In terrestrial zoology, megafauna (from Greek μέγας megas "large" and New Latin fauna "animal life") are large or giant animals. Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives.
