An early Cambrian tunicate from China
Article Abstract:
Research is presented describing the possible discovery of a tunicate Cheungkongella ancestralis from the Chengjiang fauna of China's Lower Cambrian. The details of tunicate evolution could be useful in understanding the origin of chordates and vertebrates.

A pipiscid-like fossil from the Lower Cambrian of south China
Article Abstract:
An important source of information in fossil preservation is the Burgess Shale-type faunas, which provide insights into metazoan phylogeny. Some hitherto enigmatic fossils have unique character-state combinations that can be interpreted as defining major stem-groups. A possible pipiscid is described from the Lower Cambrian of south China. It is a metazoan previously seen only from the Upper Carboniferous.

Lower Cambrian vertebrates from south China
Article Abstract:
There is a lack of fossil record of Cambrian chordates, however two distinct types of agnathan from the Lower Cambrian Chengjiang fossil-Langerstatte of the Quiongzhusi Formation at Haikou, Kumming City, Yunnan, have been described. One form is lamprey-like, and the other is closer to the more primitive hagfish.
