摘要:褶齿豕脊齿象(Choerolophodon corrugatus)是豕脊齿象属在巴基斯坦西瓦里克群发现的唯一种。其首次发现是在西瓦里克亚群下部的卡米列组(中新世晚期), 而后大量见于西瓦里克亚群中段的道克派珊组(中新世晚期至上新世早期)。本次报道的褶齿豕脊齿象新材料发现于道克派珊模式产地及其邻近区域。发现的材料包括象牙、下颌、上颌碎片以及一些乳前臼齿和臼齿。新材料与欧洲的Ch. pentelici的牙齿特征极其相似,但在头骨和下颌特征上有所区别

Abstract   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.    
Keywords   Siwalik Group, Dhok Pathan Formation, Miocene, Pliocene, Choerolophodon
