Fossils of tarsiiform primates have been found in Asia, Europe, and North America (with disputed fossils from Northern Africa), but extant tarsiers are restricted to several Southeast Asian islands. The fossil record indicates that their dentition has not changed much, except in size, over the past 45 million years.
Generally accepted members of this infraorder include the living tarsiers, [1] the extinct omomyids, two extinct fossil genera, and two extinct fossil species within the genus Tarsius. [3] As haplorhines, they are more closely related to monkeys and apes than to the strepsirrhine primates, which include lemurs, galagos, and lorises. Order Primates
Philippine tarsier (Carlito syrichta). Tarsiiformes is an infraorder of small primates.It contains a single extant family, Tarsiidae, and members of this infraorder are called tarsiiformes, with members of the family named tarsiers.
The tarsier lineage is known to have split from other primate lineages around 58 mya, but it could very well be much earlier. Scientists have discovered tarsiid fossils from Asia dating from the Eocene to the Miocene. [4] Multivariate analyses have shown the T. lariang is significantly
Articles relating to the Tarsiers (Tarsiidae), haplorhine primates of the family Tarsiidae, which is, itself, the lone extant family within the infraorder Tarsiiformes. Although the group was, prehistorically, more globally widespread, all of the species living today are restricted to Maritime Southeast Asia , predominantly being found in ...
Horsfield's tarsier is a host of the acanthocephalan intestinal parasite Moniliformis tarsii. [17] Like all tarsiers, Horsfield's tarsiers are vertical clingers and leapers, known for extraordinary leaping abilities. An individual will mainly support itself with its feet and the tail, both exerting enough force to hold the individual in place.
This is a list of fossil primates—extinct primates for which a fossil record exists. Primates are generally thought to have evolved from a small, unspecialized mammal, which probably fed on insects and fruits. However, the precise source of the primates remains controversial and even their arboreal origin has recently been questioned. [1]
Altiatlasius koulchii, potentially the oldest known euprimate, [1] is known only from ten isolated upper and lower molars and a fragment of a mandible. [a] [4] [5] These fossils date to the Late Paleocene, approximately 57 million years ago, [b] and come from the Jbel Guersif Formation in the Ouarzazate Basin of Morocco. [4]
