Paperback. Condizione: New. Print on Demand. This book compiles a series of studies on the fossilised remains of early vertebrates that lived during the Permian era, some 280 million years ago, in what is now New Mexico, USA. These remains, primarily from the families Diadectidae and Aspidosauridae, offer insights into the diversity and characteristics of some of the earliest vertebrates. The studies describe the anatomy of the animals, their behaviour, and their place in the evolutionary history of vertebrates. The authors were able to conclude that the Permian period was a time of great diversification for vertebrates, with some species developing adaptations for life on land.
