摘要: 记述了丹江库区周围发现的三种兔形类化石:产在丹江二级阶地基座岩层中的淅川跳兔(新种)Alloptox xichcuanensis sp. nov.个体小, 形态较早中新世中期的A. minor原始,其时代可能是早中新世早期,同时详细讨论了Alloptox的进化和分类;发现于台子山林场裂隙堆积物中的进步上新五褶兔(新种)Pliopentalagus progressivus sp. nov.个体为该属已知各种中最大者,形态较已知种更接近于现生的Pentalagus,它的时代可能为上新世末或更新世初;产于郧县

Abstract: Three species of lagomorghs found in 1994 from Danjiang Reservoir area in Hubei and Henan are described in the present paper. Alloptox xichuanensis sp. nov. represented by an upper and a lower jaw is considered to be the earliest record of the genus. One p3 is her referred to Ochotonoides complicidens. Another p3 is treated to a new species, Pliopentalagus progressitus, which may be the most advanced representative of the genus. The fossil — bearing beds are also discussed herein.
