Long before whales, giant reptiles ruled the seas: plesiosaurs, mosasaurs, and their strange kin. Samuel Williston explains how these water reptiles were built and how they lived, from skull to paddle, across the ages. Authoritative paleontology made readable. Dive into the age of the great sea reptiles.

Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
