Recommended.

Two very good books that I would recommend to anyone interested in the evolution of early amphibians, tetrapods and the emergence of vertebrates on to land are:

Clark, J.A. (2002) Gaining Ground: the Origin and Evolution of Tetrapods. Indiana University Press, Bloomington.

Zimmer, C. (1999) At the Water’s Edge. Touchstone, New York.
