Fossils from Egypt from key groups in Eocene-Oligocene extinction
Researchers discovered a previously undocumented extinction event that followed the transition between the Eocene and Oligocene periods and affected animals in Africa. Fossils from the Fayum Depression in Egypt from key groups in this extinction include: (upper 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.
