The Study Of New Materials Of Arthropods And Vetulicola In Jianhe Biota Of Guizhou

The Jianhe biota is a Burgess shale-type biota in the Cambrian.It is located in the upper part of the "Tsinghsutung" Formation and the strata are dominated by limestone and shale,belongs to the transition zone between the Cambrian of Yangtze area and the Jiangnan area in the Balang Village,Jianhe County,east of Guizhou Province.The biota is rich in animal species: Porifera,Cnidaria,Vermes,Brachiopoda,Arthropods,Vetulicolida,Echinodermata etc.This article focuses on the Arthropods and Vetulicolida of the morphological and systematic classification studies were carried out on the genus species of the animal in the Jianhe biota,and 4 genus of 2 conformis and 2 unspecified species were described.They were the Qingquanella cf.hubeiensis and Amplectobleua cf.symbrachiata and ? Hurdia sp.of the Anomalocarida,and the Vetulicola sp.The research in this paper makes the Jianhe biota combination more abundant,the arthropods increase the Qingquanella,Amplectobleua,and determine the Vetulicola of Vetulicolida.Bradoriida,Anomalocarida and Vetulicola in the Jianhe biota are the first research and important new materials.The Qingquanella first emerge in the Cambrian Series 2,Stage 3,Shuijingtuo Formation,Yichang,Hubei Province,and has extended the Stage 4,“Tsinghsutung” Formation,Jianhe,Guizhou Province.The Shipai Formation of Yichang,Shennongjia Hubei Province and the Xinji Formation of Luonan,Shaanxi Province have their output.The Anomalocarida appeared in the Chengjiang biota of the Yu'anshan Formation in the Chengjiang,Yunnan Province.This class has extended to the Ordovician and Silurian,Amplectobleua is mainly found in the the Cambrian Series 2,Stage 3,Such organisms are found in the Stage 4 of the "Tsinghsutung" Formation,the Kinzers Formation of Pennsylvania,the Burgess shale biota.The Vetulicola is mainly produced in the Yu'anshan Formation and Stage 4 of the Wulongqing Formation from the Chengjiang,Yunnan Province,and "Tsinghsutung" Formation,Jianhe,Guizhou.The "Tsinghsutung" Formation in Jianhe,Guizhou Province found that Qingquanella,Amplectobleua,and Vetulicola not only expanded their geographic distribution in the fourth order of the Cambrian second system,but also provided materials for studying their evolution and migration.As a window of the Cambrian biological radiation,the Jianhe biota,not only a transitional biota between the Balang biota and the Kaili biota,but also a radiation from the Chengjiang biota to the the Burgess shale biota.The study of Bradoriida,Anomalocarida and Vetulicolida provides an important basis for the composition and evolution of the Jianhe biota.
