Philippine Tarsier

Fossils of tarsiiform primates are found in Asia, Europe, and North America, with disputed fossils from Africa, but extant tarsiers are restricted to several Southeast Asian islands, including the Philippines, Sulawesi, Borneo, and Sumatra. The fossil record indicates their dentition has not changed much, except in size, in the past 45 million years.
Within the family Tarsiidae, there are two extinct genera, Xanthorhysis and Afrotarsius. However, the placement of Afrotarsius is not certain, and is sometimes listed in its own family, Afrotarsiidae, within the infraorder Tarsiiformes, or considered an anthropoid primate.
So far, three fossil species of the genus Tarsius are known from the fossil record:
- Tarsius eocaenus is known from the Middle Eocene in China.
