The American horseshoe crab that comes ashore on the East Coast in vast numbers to mate and nest is much the same creature that haunted the coast before the time of the dinosaurs. It is among the world's most intensely studied marine invertebrates, critical to our understanding of many groups of organisms, both modern and extinct, and crucial to the ecology of large estuaries such as the Delaware Bay. Some stocks of this great survivor, whose ancestors made it through the mass extinction some 286 million years ago, have been severely depleted today because of overfishing and habitat...

With its massive head, enormous jaws, and formidable teeth, Tyrannosaurus rex has long been the young person's favorite creepy carnivore in the Mesozoic zoo. Nor has T. rex been ignored by the scientific community, as this new collection amply demonstrates. Scientists explore such questions as why T. rex had such small forelimbs; how the dinosaur moved; what bone pathologies tell us about life in the Cretaceous; and whether T. rex was a predator, a scavenger, or both. There are reports on newly discovered skeletons, on variation and sexual dimorphism, and how the big beasts chewed. The...

Like the original edition, first published in 1984, the revised edition of Kansas Geology is heavily illustrated with photographs and line drawings, many of them in full color, plus maps and...

Life in Stone is the first booik to focus on British Columbia's fossils. Each of its chapters is written by a specialist for a general audience, and each is devoted to a separte fossil group that is particularly well represented in the province.

British Columbia is a vast storehouse of fossils, many of which date back a billion years. Thousands of exposures of sedimentary rocks throughout the province contain fossil shells, scales, bones, teeth, and leaves. Some of the fossils are large and striking, among them the bones of mammals and reptiles, entire ammonoids, and complete...

Praise for the first edition:

"A gift to serious dinosaur enthusiasts" --Science

"The amount of information in these] pages is amazing. This book should be on the shelves of dinosaur freaks as well as those who need to know more about the paleobiology of extinct animals. It will be an invaluable library reference." --American Reference Books Annual

"An excellent encyclopedia that serves as a nice bridge between popular and scholarly dinosaur literature." --Library Journal (starred review)

"Copiously illustrated and scrupulously up-to-date... the book reveals...

With their spectacularly enlarged canines, sabertooth cats are among the most popular of prehistoric animals, yet it is surprising how little information about them is available for the curious layperson. What's more, there were other sabertooths that were not cats, animals with exotic names like nimravids, barbourofelids, and thylacosmilids. Some were no taller than a domestic cat, others were larger than a lion, and some were as weird as their names suggest. Sabertooths continue to pose questions even for specialists. What did they look like? How did they use their spectacular canine...

This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the...

Perhaps nudged over the evolutionary cliff by a giant boloid striking the earth, the incredible and fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins.

The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of...
