| 英文摘要 | We report on a newly born mandible and an adult pes of Platybelodon danovi from the Dingjiaergou fauna, China. Tooth succession in Platybelodon is very specialised, including a tendency to lose the dp2, an early loss of the di2 perhaps at the foetal stage, a tendency to lose the p3 and a tendency to reduce the P4 and the p4. The pes is also specialised, with metatarsals IV and III nearly equal in length, metatarsal IV less twisted than metatarsal III, metatarsals IV and III more anteroposteriorly compressed and metatarsals aligned nearly at the same level. These findings have important paleobiological significance. First, the relatively derived tooth succession of Platybelodon occurred at a relatively early geological time, thus representing an early evolution of tooth succession independent from other proboscideans. Second, the gravity vector of the hind limb of Platybelodon shifted towards metatarsal IV, and the modified standing posture may imply a lightly built body and rapid locomotion relative to other gomphotheres and elephants. These new paleobiological data add to our knowledge of the life history of Platybelodon and the diverse adaptations of ancient proboscideans. |
