摘要
系统研究了闽西永安丰海地区二叠系上部及三叠系下部的双壳类动物群面貌、层位及组合,并与国内外相当的地层进行了对比,阐明了该双壳动物群在二叠-三叠系界线划分中的地层意义.描述了15属24种(其中5新种)、5未定种.
The uppermost Permian and Lowermost Triassic bivalves described here were collected by the author in 1987 from Fenghai area (mainly Jueqian section) in Yong'an, Fujian. Altogether 24 species (including 5 new species) assigned to 20 genera, together with the bivalve assemblage and the Permian-Triassic boundary are studied and discussed in this paper. The latest Permian Hunnanopecten exilis zone and the earliest Triassic Claraia wangi zone are recognized, while the boundary between Permian and Triassic is drawn at the base of Bed 46 with the Hypophiceras fauna in this area.
