J. R. E. MILLS 《Zoological Journal of the Linnean Society》1984,82(1-2):189-205
The paper describes the molar teeth of a primitive therian mammal from the early Jurassic of S. Wales. The teeth are all isolated with largely intact crowns but with the roots usually broken. An attempt is made to reproduce a molar series and it is suggested that the animal has five constant molars with a sixth which was inconstant in size and probably not always present. The teeth exhibit a number of very primitive features. The animal may well be congeneric with Kuehneotherium praecursoris , from which it differs in a number of details. 相似文献
