PRIMITIVE RHINOCEROTID FOSSIL FROM THE MIDDLE EOCENE OF YUANQU BASIN, SHANXI

HUANG Xue-Shi

Abstract  Prohyracodon cf. P. meridionale, represented by a fragmentary upper jaw with M1?M3(IVPP V 13101), is briefly described in the present paper. The fossil was found at Huoshipo near Guojia Village, Wangmao Town, Yuanqu County. The upper molars of V 13101 resemble those of P. meridionale in general tooth morphology and in size, but differ mainly in lacking distinct antecrochet. The age of the fossil-bearing bed may be of Middle Eocene Irdinmamhan as revealed by associated fossil mammals.
Key words  Yuanqu, Shanxi; Middle Eocene; Prohyracodon
