Fossils of Kenya

Arsinoitherium (Arsinoe II's beast) is an extinct genus of paenungulate mammals belonging to the extinct order Embrithopoda. It is related to elephants, sirenians, and hyraxes. Arsinoitheres were superficially rhinoceros-like herbivores that lived during the Late Eocene and the Early Oligocene of North Africa from 36 to 30 million years ago, in areas of tropical rainforest and at the margin of mangrove swamps. A species described in 2004, A. giganteum, lived in Ethiopia about 27 million years ago.

Percrocuta is an extinct genus of percrocutid hyena. It lived in Eurasia and Africa, during the Miocene epoch.

Kubanochoerus is an extinct genus of large, long-legged suid artiodactyl mammal from the Miocene of Eurasia and Africa.

Metapterodon ("next to Pterodon") is an extinct genus of hyainailourid hyaenodonts of the subfamily Hyainailourinae, that lived in Africa during the early Oligocene to early Miocene. Fossils of Metapterodon were recovered from Egypt, Uganda, Elisabeth Bay Formation in Namibia, and Rusinga Island and Karungu in Kenya.

Losodokodon ("Losodok tooth") is an extinct genus of large herbivorous mammals belonging to the family Mammutidae. It was first described in 2009 by David Tab Rasmussen and Mercedes Gutiérrez from fossils found in the Erageleit Formation of northwestern Kenya. Losodokodon lived during the Late Oligocene, between 27 and 24 million years ago. It is known from isolated molars and premolars. Dental mesowear suggests a browsing diet.

Australosomus (meaning "southern body") is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch in what is now Greenland, Kenya, Tanzania, Madagascar, South Africa and Canada (British Columbia). thumb|left|Australosomus merlei fossil

Ekembo is an early ape (hominoid) genus found in 17- to 20-million-year-old sediments from the Miocene epoch. Specimens have been found at sites around the ancient Kisingiri volcano in Kenya on Rusinga Island and Mfangano Island in Lake Victoria. The name Ekembo is Suba for "ape" or "monkey".
