Phylogenetic tree of the primates Notharctus. The evolutionary history of the primates can be traced back 57-90 million years. [1] One of the oldest known primate-like mammal species, Plesiadapis, came from North America; [2] another, Archicebus, came from China. [3]
Together with Paralouatta marianae from Cuba, it is the oldest known New World monkey of North America. [2] Fossils of Panamacebus, a left upper first molar and lower premolar, [3] were uncovered from the Las Cascadas Formation, of which tuffs were analyzed providing an age of 20.93 ± 0.17 Ma, [4] of the Panama Canal Zone.

The smallest Old World monkey is the talapoin, with a head and body 34–37 centimetres (13–15 in) in length, and weighing between 0.7 and 1.3 kilograms (1.5 and 2.9 lb). The largest is the male mandrill, around 70 centimetres (28 in) in length, and weighing up to 50 kilograms (110 lb) [ 6 ] Old World monkeys have a variety of facial features ...
Skull at the Royal Tyrell Museum in Drumheller, Alberta, Canada. Bison latifrons is thought to have evolved in North America from Bison priscus (sometimes called the steppe bison) another prehistoric species of bison that migrated across the Bering Land Bridge around 195–135,000 years ago, before dispersing southwards around 130,000 years ago.
Under this theory, the squirrel monkey's ancestors arrived in Central America between 3 and 3.5 million years ago, but could not compete effectively when the ancestors of the other species arrived in Central America about 2 million years ago. The other species thus drove the squirrel monkey out of most of its original range.
Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla.It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America.
This suggests the primitive platyrrhine ancestors of Branisella came to South America from Africa. Other features, however, suggest that it may have been related to the omomyids, an extinct group of tarsier-like primates found in North America, among other places. [5] Branisella has an estimated body mass of 1,000 g (35 oz). [1]
