| Abstract: | This present paper discusses a new species of Stegodon which occurred in Panji District, Anhui Province. Diagnosis of the new species Stegodon Panjiensis sp. nov. is of broken upper jaw of rather median size with a left second molar(1M2). It consists of seven ridge plates, loxodont in pattern of the ridge crest of this molar. The posterior part of the anterior talon is connected the next ridge. plate Each ridge crest consists of 7-8 mammillae. L. F. =3. 6. The crests are comparatively high (around 45mm),Median sulcus presents at all ridge plates and cement presents in posterior valleys between the two neighbouring ridge plates. The enamel layer thickness is 3. 5-4 mm. Posterior talon does not incline to front and taper backward. |
