Gallimimus

Gallimimus was an Ornithomimid from the Late Cretaceous in Mongolia, it had long legs and presumably could have run extremely fast. Its name means "Bird Mimic". It may have been a herbivore, although it is much more likely it was an omnivore, eating small prey such as insects and lizards. The in-game model was created by EXDragonith, and it will be ride-able. It is mostly orange and brown, with large white eyes true to the style of this mod. It will be about 4 blocks tall when fully grown. It has not been added yet, but presumably will be in update 6.2.
