摘要： Choerolophodon corrugatus is the only species of the genus Choerolophodon found in the Siwalik Group. Its first appearance is in the Kamlial Formation (Middle Miocene) of the Lower Siwalik Subgroup and it is most abundant in the Dhok Pathan Formation of the Middle Siwalik Subgroup (Late Miocene to Early Pliocene). New remains of Choerolophodon corrugatus have been recovered from the Dhok Pathan type locality and its adjacent areas. The specimens include tusks, mandible and maxillary fragments, and deciduous premolars and permanent molars. The Siwalik species shows great affinity with the European species Ch. pentelici in dentition and differs in the cranial and mandibular characteristics.
