Family

† EOSIMIIDAE
Beard et al., 1994

THE EOSIMIIDAE are a family off of primates, generally considered to be the oldest and most basal of monkeys families. The first representatives of this family appeared during the Eocene, 45 million years ago. We found Eosimiidae fossils in China and Burma. They belong to very small species. This family would have died at the start of the oligocene.

Phylogeny of current primates infra-orders, according to Perelman et al. (2011) ^{[ first ]} :

The Eosimiidae family has three consensual genres:

• Genre † Eosimias , Beard et al. , 1994 : from 45 to 40 mA, China and Burma
  • Eosimias sinensis , Beard et al. , 1994 : 45 ma, jiangsu (chine) ^{[ 2 ]}
  • Eosimias centennicus , Beard et al. , 1996 : Shanxi (chine) ^{[ 3 ]}
  • Eosimias dawsonae , Beard & Wang, 2004 : 42 ma, shanxi et Henan (chine) ^{[ 4 ]}
  • Eosimias paukkaungensis , Dressing et al. , 2005 : Burma ^{[ 5 ]}

• Genre † Phenacopithecus , Beard & Wang, 2004 : 42 mA, China
  • Phenacopithecus krishtalkai , Beard & Wang, 2004 : Shanxi et Henan (chine) ^{[ 4 ]}
  • Phenacopithecus xueshii , Beard & Wang, 2004 : Shanxi et Henan (chine) ^{[ 4 ]}

The possible affiliation of other fossil taxes to this family remains discussed:

• Genre † Nosmips , Seiffert et al. , 2010
  • Nosmips aenigmaticus , Seiffert et al. , 2010 : 37 ma, Egypt ^{[ 8 ]}

The discovery in China of the oldest and the oldest and the best known monkeys indicates that the monkeys are probably from Eastern Asia, from 45 mA. The monkeys only appear in Africa from around 40 my .
