Einiosaurus was a medium-sized herbivorous centrosaurine ceratopsian dinosaur from the Upper Cretaceous (Campanian stage) of northwestern Montana. The name means 'buffalo lizard', in a combination of Blackfeet Indian eini and Latinized Ancient Greek sauros; the specific name (procurvicornis) means 'with a forward-curving horn' in Latin.
Eggman has invaded the islands where the dinosaurs live and now he wants to inject them with a dangerous weapon, metal virus. Team Sonic, along with other researchers, must stop the Eggman and the virus before all the dinosaurs are exposed to it.
