Sivachoerus (Artiodactyla, Suidae, Tetraconodontinae) from the Pliocene of Myanmar
- The phylogenetic status of Sivachoerus is re-evaluated according to the new materials recovered from the central Myanmar. Sivachoerus had also been known from the Pliocene Siwalik sediments of Indian Subcontinent. Compared to Siwalik specimens, Myanmar specimens are poorly known and have not been confirmed their geological age yet. New evidence for the discovery of Sivachoerus from the Irrawaddy Formation presumed that Sivachoerus has appeared during the Pliocene in Myanmar, Southeast Asia. Dental morphology and chronology of Sivachoerus strongly support the 'African origin' hypothesis than the 'Asian origin' of this genus. Sivachoerus probably evolved from the African Nyanzachoerus rather than the Asian Conohyus, during the Late Miocene, and migrated to Asia during the late Miocene.
