FROM A FOSSIL ASSEMBLAGE TO A PALEOECOLOGICAL COMMUNITY Time, Organisms and Environment based on the Kaili Lagerstatte (Cambrian), South China and Coe

The Cambrian Period (542 to 488 Ma) marks the §beginning of an abundant fossil record, and the §Burgess Shale Biota was the first fully described §fossil assemblage that contains a relatively §complete picture of a benthic Cambrian community. §More Burgess Shale-type (BST) fossil assemblages §have been discovered since then and are ready to be §utilized to test hypotheses about the ecology of the §Cambrian explosion, which is the most important §event in the evolution of metazoans. This book §focuses on the Kaili Biota §(http://hdl.handle.net/1811/24227), an important §deposit bridging the stratigraphic gap between §Chengjiang Biota and Burgess Shale Biota. It allows §us to gain a more complete understanding of the §Cambrian life through the window of BST deposits. §The book is divided into four parts. Part 1 includes §stratigraphic background of Kaili Formation. Part 2 §contains discussions on taphonomy. Part 3 provides §new observation for Cambrian paleoecology, including §animal-substrate relations, spawning habits, teiring §community, and faunal succession. Part 4 presents §hypotheses on arthropod, echinoderm evolution, and §the evolution of biosphere.
