摘要: 1962年在我国广东南雄盆地首次发现了阶齿兽类化石(周明镇等,1973;郑家坚等,1973),随后在安徽潜山、湖南茶陵、陕西石门、江西大余等地的中古新世地层中相继发现该类动物的化石材料,尤其是在广东南雄、江西大余和湖南茶陵三个地点,有大量的阶齿兽类化石产出。阶齿兽类在中古新世时在亚洲南部是广泛分布的。本文记述的阶齿兽材料是2003年在江西池江盆地发掘到的,此标本与已知的阶齿兽属中各种均有明显差别,故建立一新种——丁氏阶齿兽(Bemalambda dingae sp.nov.)。

Abstract: Bemalambda was first found from Nanxiong Basin, Guangdong Province in 1962 (Chow et al. , 1973 ; Zheng et al. , 1973) . The subsequent discoveries of bemalambdids from the Middle Paleocene of Qianshan of Anhui, Lingcha of Hunan, Shimen of Shaanxi, Chijiang of Jiangxi indicate that Bemalambda had a wide distribution in the Middle Paleocene of southern China. The specimen described in this paper was found from Chijiang, Jiangxi in 2003 and is distinctly different from those of other species in the genus. It represents a new species, Bernalambda dingae sp. nov.
