Alternate Dinosaurs: Abelisaurs

History
The abelisaurids evolved in the mid Jurrasic period, but didn't diversify until the mid Cretaceous about 95 MYA. However, that was in the southern hemisphere, because around that time, they went extinct in the northern hemisphere due to competition. During the late Cretaceous, they lived in South America, Africa, India and Madagascar.

They thrived in India until the early Miocene, about 23 MYA when India started to collide with Asia. By the late Miocene, about 8 MYA, the connecting was completed, and tryannosaurs started to populate; by the early Plilocene, about 4 MYA, they were extinct there. South America's species were wiped out in the Pliocene to, when a meteorite struck close to the continent 3.3 million years ago. Only Africa and Madagascar held healthy populations of these advanced ceratosaus.

6.5 million years ago the Mediterranean Sea evaporated. A series of tall mountains, their slopes blanketed in lush greenery, and thanks to the Sahara being more fertile back then, provided a welcome refuge for dinosaurs that ventured into the salt filed basins from Europe and Africa. Then, 5.3 million years ago, the waters of the northern Atlantic burst through the straits of Gibraltar, quickly filling the Mediterranean basin. The large became small, including the abelisaurids.
