Alternate Dinosaurs: Onithomimods

==History==
Ornithomimods originated in the early cretaceous from an ancestor named †Pelecanimimus, but they didn't diversify until the late Cretaceous. In our own timeline, the ornithomimod's history ends at the end of the Cretaceous, but in THIS timeline, the ostrich dinosaurs continued through the end of Mesozoic and into the Cenozoic; with little trouble. However, they almost became extinct in the Palegocene and Early Eocene due to dense forests becuase the couldn't adapt to such a different biome, but the Eocene-Oligocene mass extinction saved them due to the return of open space for running. They greatly diversified even more during the Miocene when spaces became even more open. During the mid Pliocene, they crossed over several deserts into Africa. When the Central American land-bridge formed, they crossed into South America.
==Families==
*Trotters: this familiy of onithomimids have a life-style very similar to their Late Cretaceous ancestors, except their teeth have evolved for a diet of grass.
*Crestomimod: this group of onithomimids live exclusivley in the Americans and have crests like a cassowary.
*Ostrichmimod: these look like ostritches with arms.
