WA Museum Records and Supplements | Updated 1 decade ago

Abstract - A new species of Stenothecoides, S. yochelsoni sp. nov., is described from the Early Cambrian Huangshandong Member of the Tongying Formation in Eastern Yangtze Gorge, western Hubei, China. This species is one of the new members of the Yangtze micromolluscan fauna. The occurrence indicates that the first appearance of Stenothecoides can be dated to the earliest Cambrian, and it is probably the earliest record of the genus. Two other Early Cambrian species, Bagenovia cf. sajanica Horny and Stenothecoides sp., are described from the Xidashan Formation of Kuruktag, Xinjiang, China.
