This enormous, elephant-like monster lived during the Pleistocene era.


The Megalodon, a gigantic animal that resembled a great white shark, is most likely descended directly from the kind that exists today.


It is a sea species, and reptiles with large jaws and short necks, like Monsters, were used to devour their prey.


They belonged to the Phorusrhacidae family and were referred to as "terror birds" informally.
