Gao, Y., Shi, G.R. Peng, Y., March, 2009. A new bivalve fauna from the Permian-Triassic boundary section of southwestern China. Alcheringa 33, 33-47. ISSN 0311-5518. A new marine bivalve fauna from the continuous Upper Permian Longtan Formation to Lower Triassic Yelang Formation of the Zhongzai section in southwestern China is documented. Four bivalve assemblages spanning the Permian-Triassic boundary are recognized and regionally correlated in South China. The bivalve assemblages changed from elements dominated by Palaeozoic types to those dominated by Mesozoic types. Three new species, Claraia zhongzaiensis sp. nov., Claraia sp. nov. 1 and Claraia sp. nov. 2, are described.
