寒武纪三叶虫Sinoproceratopyge kiangshanensis Lu的卷曲与蜕壳
Enrollment and Exuviation of the Cambrian Trilobite Sinoproceratopyge kiangshanensis Lu
摘要
Abstract
An enrolled meraspid trilobite specimen of Sinoproceratopyge kiangshanensis Lu,collected from the upmost part of Furongian of Cambrian in Jiangshan,Zhejiang Province,is described.It is well preserved except the thoracic segments covered by the cephalon.With the free cheek splitting from the fixed cheek,it is believed that in the process of exuviation,the enrolling was an inevitable movement.With a big cephalon,small pygidium and a few thoracic segments,the Sinoproceratopyge kiangshanensis is considered to be completing on enrollment,probably then a "hemispiral enrollment".The enrollment is similar to that of the trilobites from Upper Cambrian of Missouri in America,but different from that of Stephanocare from Liaoning.关键词
