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.[1][2] The only known species, A. achilles, was a small primate, estimated to weigh about 20–30 grams (0.7–1.1 oz), and is the only known member of the family Archicebidae. When discovered, it was the oldest fossil haplorhine primate skeleton found,[3][4] appearing to be most closely related to tarsiers and the fossil omomyids, although A. achilles is suggested to have been diurnal, whereas tarsiers are nocturnal. Resembling tarsiers and simians (monkeys and apes), it was a haplorhine primate, and it also may have resembled the last common ancestor of all haplorhines.
