OverviewPlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Since 1990 there has been intense debate among paleontologists about the evolution in the Early Cambrian period of the super-phylum Lophotrochozoa, which is thought to include the modern molluscs, annelid worms and brachiopods, as well as their evolutionary aunts and cousins . The name halwaxiid was formed by combining the names of two members of the proposed group, Halkieria and Wiwaxia. The group was defined as a set of Early to Mid Cambrian animals that had: a chain mail coat of three concentric bands of small armor plates that are called sclerites; in some cases, a small cap-like shell at the front end and in some cases both ends.
