| Abstract: | Two genera and three species of Middle Oligocene insectivora from Ulantatal,AlxaZouqi,Nei Mongol are described in the present paper.The material consists of lowerjaws and teeth in various states of preservation.No upper jaws and teeth were collec-ted in the area.24 of the specimens belong to Amphechinus rectus(Matthew and Gran-ger,1924).They show a great range of variation in size in this species,though,mor-phologically,these jaws and teeth are essentially the same.An isolated M_1,much lar-ger in size,is tentatively referred to Amphechinus cf.rectus.Another fragmentary lowerjaw with small teeth,relatively short trigonid in the lower molars,rooted and fairly welldeveloped talonid in M_3 is undoubtedly perta-ined to Palaeoscaptor acridens Matthew andGranger,1924,which has not been definitely found in China before.In agreementwith McKenna and Holton(1967)the two original species of Palaeoscaptor should beassigned to two genera——Palaeoscaptor and Amphechinus.Also the material gives somenew data to the age of the fossil-bearing bed. |
