摘要: 本文记述了一种产自山东五图盆地的多瘤齿兽,在牙齿形态上类似在古新世绝灭的Mesodma和Mimetodon,取名为道森拟间异兽(Mesodmops dawsonae)。这是亚洲晚白垩世—早第三纪地层中首次发现新斜沟齿兽类(neoplagiaucid)多瘤齿兽。文中也简单地讨论了我国目前缺少直接与大部分五图哺乳动物有关的古新世哺乳动物的原因。

Abstract: This paper places on record Mesodmops, a new genus of a multituberculate family of mammals, Neoplagiaulacidae. Previously known multituberculate materials from early Tertiary of Asia have been all allocated into the family Taeniolabididae. No ptilodontoid multituberculate has been reported in this continent until the discovery of the Wutu specimens. The Wutu specimens were collected from Wutu Formation, Lower Eocene in 1992 and are concurrent with Changlelestes dissetiformis (Insectivora, see Tong and Wang, 1993), ischyromyid rodents, carpolestid primates, primitive perissodactyls and other mammals.
