摘要： 记述了在湖北省房县罗家沟始新世地层中新近发现的哺乳类，其中包括踝节目豕齿兽科豕齿兽属一新种—房县豕齿兽(Hyopsodus tangxianensis sp. nov.)。依据该新种的进化水平，进一步确定产化石的油坪组的地质时代为早始新世，但就化石层本身来说，很可能是早始新世晚期。
Abstract: Hyopsodus fangxianensis sp. nov. and Ctenodactyloidea fame, gen. and sp. indet. represented by fragmentary lower jaws are described in the present paper. The fossils were found near the village Luojiagou, 10 kilometers away northwest to FangXian city, where exposes a series of reddish-brown and purplish-red mudstone and siltstone with greyish-green sandstone or siltstone intercalations.
Hyopsodus is the common animal in the Early and Middle Eocene of North America. Outside North America only in Asia it was found in the past decades (Dashzeveg, 1977; Zhai, 1978; Tong, 1989). Up to now only three species of Hyopsodus have been described from Asia, and all of them are represented by fragmentary unique specimens. So each specimen of this genus discovered in Asia is especially precious. The discovery of Hyopsodus in Fangxian not only further indicates the genus existing in Asia but- also enriches the genus composition and extends the distribution south to the Yangtze River valley.
