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]
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]

[111] Several of these species are preyed upon by the common chimpanzee. [119] In South America, squirrel monkeys associate with capuchin monkeys. [120]

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 ...
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 Virginia opossum, Didelphis virginiana, the only marsupial in temperate North America. Armadillos, opossums and porcupines are present in North America today because of the Great American Interchange. Opossums and porcupines were among the most successful northward migrants, reaching as far as Canada and Alaska, respectively.
