摘要: The specimen described in the present paper was discovered from the diatomaceous shale of the “Shanwang Series”at Hsiehchiaho in Linchu county, Shantung Province in 1973. The material only includes left upper fourth premolar and first molar (Shanghai Museum of Natural History Cat. No. SM. 1020).
According to the characters of the teeth, it is obvious that the Hsiehchiaho specimen belongs to Palaeotapirus, and is similar to Palaeotapirus helvetius of Europe in size and general structure of the teeth, but differs mainly from the latter in having strong parastyle and absence of the lingual cingulum in M1. Japanese Palaeotapirus yagii is known by the lower cheek teeth only, so that the comparison between P. yagii and ours` is impossible. Therefore, we establish this specimen as a new species—palaeotapirus xiejiaheensis. The age of the fossil-bearing beds seems to be of Middle Miocene.
The discovery of the Palaeotapirus in China is important in studying the evolution of Tapiroidea. It shows that Tapiroidea in Asiatic continent may be a independent phyletic line.
