Coniferous Fossil Woods from the Jogyeri Formation (Upper Triassic) of the Nampo Group, Korea

Abstract

Ninety–four fossil woods were collected from the Upper Triassic Jogyeri Formation of the Nampo Group in the County of Cheongyang-gun, Chungcheongnam- do Province, Korea. Eight of the specimens were preserved well enough to identify them down to species or genus. All were coniferous woods. On the basis of their detailed anatomical features, four specimens were identified as Xenoxylon phyllocladoides Gothan and the other four as Agathoxylon sp. Therefore six taxa of fossil woods, Cedroxylon regulare Göppert, Xenoxylon phyllocladoides Gothan, X. latiporosum (Cramer) Gothan, X. japonicum Vogellehner, Phyllocladoxylon heizyoense Shimakura and Agathoxylon sp., have now been reported from the Early Mesozoic Daedong Supergroup in the Korean Peninsula.

“…It was only at the end of the twentieth century that Chinese Mesozoic wood research was reinvigorated (Du, 1982;Zheng and Zhang, 1982;Duan, 1986;Duan et al, 1995;Zhang and Chang, 1996;Zhang et al, 1999Zhang et al, , 2000aDing, 2000a,b;Ding et al, 2000a,b;Duan, 2000;Yang et al, 2000;Zheng et al, 2001Zheng et al, , 2008Yang and Zheng, 2003). In Korea, Mesozoic palaeoxylology developed only recently (Kim et al, 2002(Kim et al, , 2005. Bibliographical data are summarized in Table 1.…”
