Archicebus
Archicebus is a genus of fossil primates that lived in the early Eocene forests (~55.8–54.8 million years ago) of what is now Jingzhou in the Hubei Province in central China, discovered in 2003.[6] Archicebus achilles exhibits similarities with simians with regard to the shape of its calcaneus and the proportions of its metatarsals, yet its skull, teeth, and appendicular skeleton resemble those of tarsiers.[7] †Adapiformes Lemuriformes (lemurs) Lorisiformes (Lorises & relatives) †Archicebus †Omomyidae Tarsiidae (tarsiers) Platyrrhini (New World monkeys) Cercopithecoidea (Old World monkeys) Hominoidea (apes) The discovery of A. achilles adds further support to the hypothesis that primates originated in Asia, and not in Africa, with many simians (a group of them) migrating to the latter continent thereafter.[3] A. achilles is estimated to have weighed 20 to 30 g (0.7 to 1.1 oz), making it comparable in size to today's smallest living primates, mouse lemurs.[8] A. achilles lived in the forests of the warm Eocene epoch, approximately 55.8 to 54.8 million years ago in a part of Asia near what now is Jingzhou, in the southern Hubei Province of China.
