Fossils from Egypt from key groups in Eocene-Oligocene extinction

Researchers found a previously undocumented extinction event that followed the transition between the geological periods called the Eocene and Oligocene and effecting animals in Africa. Fossils from Egypt from key groups in this extinction include: (left) Plesiopithecus, a lemur-like primate; (upper right) Masrasector, a carnivorous hyaenodont; (lower left) Parapithecus, a monkey-like primate; and (lower right) Gaudeamus, a guinea pig-like rodent. These fossils are from the Fayum Depression in Egypt.
