Ki208F, nodule in Yon-no-sawa stream | Futakami M. (1991) | Yezo | Probably derived from the Member U2, the lower part of the Upper Yezo Group. In the same nodule Scaphites pseudoequalis and I. cf. uwajimensis were contained abundantly. Thus, the age is probably early to middle (?) Coniacian. PJW: Inoceramus uwajimensis (= Inoceramus undabundus) zone is equivalent to the Inoceramus stantoni elsewhere, which is Late Coniacian. | "siliciclastic" | 89.3 - 85.8 Ma Late/Upper Cretaceous |
