More than 300 million years ago, during the period known as the Carboniferous, there emerged a group of four-legged animals known as synapsids. Their descendents, the therapsids, would eventually give rise to mammals.
Beginning with an introduction to the synapsids, their descendents, and the ancient world in which they lived, this book surveys their radiation, histology, and biology. It documents types of bone microstructure and their biological implications, provides insights into their biology and the evolution of endothermy in the group, and highlights areas for future research.

Index
Anusuya Chinsamy-Turan is a paleobiologist and global expert on fossil bone microstructure. She is Professor and Fellow of the University of Cape Town, South Africa, and is former director of the National History Collections, Iziko Museums of Cape Town. She is author of "The Microstructure of Dinosaur Bone: Deciphering Biology through Fine Scale Analysis" and "Famous Dinosaurs of Africa".
Ever since Nick Holton's book from 1980 we have needed an update on the biology of therapsids, and it has been Anusuya Chinsamy and her students and associates who through their bone histological work have made the greatest progress in this field.
