摘要	Molar enamel samples of three Asian coryphodontid species, Asiocoryphodon conicus Xu, 1976, Heterocoryphodon flerowi (Chow, 1957) and Eudinoceras mongoliensis Osborn, 1924, were histologically studied in order to investigate the patterns of formation of their multicusped tooth crowns and estimate their tooth crown formation times. The third upper molar crown formation times of A. conicus, H. fl erowi and E. mongoliensis were estimated to have been 2.99 ± 0.1, 3.63 ± 0.11 and 3.68 ± 0.22 years, respectively, suggesting slow growth and a long life span. In combination with the inferred body sizes, the estimated crown formation times indicate that the life history of H. fl erowi is most comparable to that of Hippopotamus amphibius among extant large herbivores, that the life history of E. mongoliensis is most properly compared with that of Ceratotherium simum, and that the life history of A. conicus was slightly shorter and faster-paced than that of Hippopotamus amphibius. Appropriate extant analogues for which data on intraspecific variation are available can be potentially helpful in better understanding the classification and phylogeny of coryphodontids, a highly diverse group of Cenozoic early mammals.
