Devonian Bivalve Faunas, Life-habits, and Biodiversity Changes in Guangxi, South China

Objective The Devonian bivalves are well developed, highly diversified and widely distributed in Guangxi. However, they have not been well studied previously, although several papers have dealt with it. Meanwhile, the biodiversity change of bivalves which is one of the most important benthos during Devonian in South China has not been studied yet. The aim of present project is focused on the study of systematic palaeontology, the life-habits, of Devonian bivalves of Guangxi.

华南长兴期至格里斯巴赫期双壳类的演替

对苏浙闽地区３个地点４个剖面的２９属（亚属）４９种（亚种）（包括１新属和４新种）双壳类的研究表明，长兴期末，华南双壳类的科属数目锐减，至格里斯巴赫期，出现了一些新的类型，按其生活方式的不同，分别属于内栖、外栖和半内栖３个类群。长兴期末华南双壳类大量消失的原因，主要是由于它们的生活环境由原来较平静变得动荡不定而引起。
