摘要: 本文记述了内蒙古乌拉乌苏始新世晚期陆龟属(Testudo)的皮骨(dermal ossicles)化石,包括足部的和尾部的。前者我国曾有记录,后者则是首次发现。结合皮骨,文中还探讨了几个有关间题。

Abstract: Some fragmentary bones of Testudo collected from Late Eocene (Shara Murun Formation) in Ula Usu area were briefly described in this paper. They include an anterior part of epiplastron, a proximal part of ilium, a foot with dermal ossicles and claw, three isolated claws, five dermal spurs of tail, a distal part of fibula and two broken bony pieces. The inner surface of anterior epiplastron thickens obviously and projects forward strongly. This is a typical character seen in Testudo. In China, a foot of Teszudo armed with dermal ossicles was reported before by C. W. Gilmore (1931), but the dermal spurs of the genus is the first occurrence this time. In view of the larger size of the bones, it seems reasonable to suppose that we have gotten a giant Testudo.
