NCSE is pleased to offer a free preview (PDF) of Donald R. Prothero's The Story of Life in 25 Fossils (Columbia University Press, 2015). The preview consists of chapter 15, "Terror of the Seas," about the discovery and the evolutionary history of Kronosaurus — "one of the largest members of a group of marine reptiles known as plesiosaurs."
Praising The Story of Life in 25 Fossils, Niles Eldredge writes, "Prothero, an outstanding paleontologist and skilled communicator, has written the best up-to-date account of the history of life as revealed by the fossil record that I have ever had the pleasure to read. ... I will keep Prothero's book handy as a core reference for years to come!"
