项目摘要

3) Studies on the fossil elasmobranchians from Hokkaido : The fossil elasmobranchyans from the Cretaceous, Tertiary and Quaternary of Hokkaido were summarized (Goto and Kimura, 1998).1) Taxonomical and morphological studies on the chondrichthyan remains from the Palaeozoic of Japan : (1) The teeth of elasmobranchs, petalodonts, cochliodonts and osteichthyes from the Akasaka Limestone (Permian) were summarized. (2) The tooth of Orthacanthus sp, (Xenacanthiformes, Elasmobranchii) from the Senmatsu Formation (Upper Permian) of Motoyoshi, Miyagi Prefecture, was described (Goto et al., 2000). (3) The teeth of Cladodus sp. and Agassizodus sp. (Elasmobranchii), the teeth of Petalodus alleghenensis and Janassa sp. (Petalodontiformes) and the tooth plates of Cyrtonodus sp., Poecilodus sp. (Cochliodontiformes) from the Ichinotani Formation (Carboniferous) and the tooth of Petalodus acuminatus (Petalodontiformes) were described. Paleobiogeographical studies and restoration of the Paleozoic fish r … More emains from Japan : The paleobiogeography of the Palaeozoic fish remains from Japan were summarized and the restorations of them were studied (Goto, 1999, 2000 ; 2002).2) Studies on the tooth remains of Chlamydoselachus from the Cretaceous and Tertiary of Japan : The tooth remains were described and the phylogeny of chlamydoselashids were considered (Takakuwa et al., 2001 ; Goto et al., 1999, 2000, 2001, 2002).4) Studies on the fish remains from the Cenozoic of Japan : (1) The upper and lower tooth plates Diodon sp. from the Miura Group (Middle Miocene) were described. (Goto and Uyeno, 2002). (2) The stratigraphical range of Carcharocles megalodon are studied (Kaneko et al., 1998 ; Yabe et al., 2000). (3) The elasmobranchyan remains from the Kakegawa Group (Pliocene) were described (Yokoyama et al., 2000).5) The Structure and development of the teeth and denticles of the first female of Megachasma pelagious from Hakata Bay were studied (Goto, 1999). Ontogeny and phylogeny of vertebrate tooth were studied (Goto and Goto, 2001; Goto, 2001). Less

3）研究来自北海道的化石Elasmobranchians：来自白垩纪ized的化石Elasmobranchyans（Goto and Kimura，1998年）.1）。总结了Akasaka石灰石（二叠纪）的骨质。 sp。（petalodontiformes）和Cyrtonodus sp。的TOTH板，来自Ichinotani组（石炭纪）的Poecilodus sp（Cochliodontiformes）研究了它们的恢复性（Goto，1999，2000; 2002）研究，从白垩纪和第三纪的衣原体遗体进行了研究，描述了牙齿残留物，衣原体壳的系统发育（Takakuwa等，2001，2001，2001，2001） ;描述了（Yokoyama等，2000）.5 Akata湾（Goto，1999）
