Umoonasaurus

Umoonasaurus is an extinct genus of plesiosaur belonging to the family Leptocleididae. This genus lived approximately 115 million years ago (Aptian-Albian) in shallow seas covering parts of what is now Australia. It was a relatively small animal around 2.5 m (8 ft) long. An identifying trait of Umoonasaurus is three crest-ridges on its skull.

Umoonasaurus is one of the dinosaurs in the game. Currently, it can only be got from either the Trade Harbor or by buying the Super Rare Plus pack, but neither can unlock the creature. This might change as it may get its' own tournament, since it has the holographic icon.
