Philippine Tarsier

- Tarsius eocaenus is known from the Middle Eocene in China.
- Tarsius thailandicus lived during the Early Miocene in northwestern Thailand.
- Tarsius sirindhornae lived during the Middle Miocene in northern Thailand.
The genus Tarsius has a longer fossil record than any other primate genus, but the assignment of the Eocene and Miocene fossils to the genus is questionable.
