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 Eocene due to dense forests, 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.
