Mosasaurs had two rows of sharp teeth. They easily snapped up prey! In this hi/lo title, readers are introduced to Mosasaurs’ body parts, behaviors, and extinction through leveled text and colorful illustrations. Along the way, features map the prehistoric world, highlight favorite foods, compare Mosasaurs’ size, and more.

A classic work from the Yale Peabody Museum of Natural History describing the mosasaurs, a group of large predatory marine lizards of the Mesozoic ​Mosasaurs have captured the imagination of readers everywhere interested in prehistoric life, and they remain a focus of paleontological study to this day. This edition of Dale Russell's Systematics and Morphology of American Mosasaurs presents the complete, classic text, generously illustrated with more than one hundred drawings and photographs, and includes a new foreword by vertebrate paleontologist Jacques A. Gauthier (Yale University and Yale Peabody Museum of Natural History).

“Excellent . . . Those who are interested in vertebrate paleontology or in the scientific history of the American midwest should really get a copy.” —PalArch’s Journal of Vertebrate Paleontology Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later. Michael J. Everhart vividly captures the history of these startling finds over the decades and re-creates in unforgettable detail these animals from our distant past and the world in which they lived—above, within, and on the shores of America’s ancient inland sea. “Oceans of Kansas remains the best and only book of its type currently available. Everhart’s treatment of extinct marine reptiles synthesizes source materials far more readably than any other recent, nontechnical book-length study of the subject.” —Copeia “[The book] will be most useful to fossil collectors working in the local region and to historians of vertebrate paleontology . . . Recommended.” —Choice
This book is the culmination of many years of research by a scientist renowned for his work in this field. It contains a compilation of the data dealing with the known stratigraphic ranges of varied behaviors, chiefly animal with a few plant and fungal, and coevolved relations. A significant part of the data consists of ``frozen behavior'', i.e. those in which an organism has been preserved while actually ``doing'' something, as contrasted with the interpretations of behavior of an organism deduced from functional morphology, important as the latter may be. The conclusions drawn from this compilation suggest that both behaviors and coevolved relations appear infrequently, following which there is relative fixity of the relation, i.e., two rates of evolution, very rapid and essentially zero. This conclusion complies well with the author's prior conclusion that community evolution followed the same rate pattern. In fact, communities are regarded here, as in large part, expressions of both behavior and coevolved relations, rather than as random aggregates controlled almost wholly by varied, unrelated physical parameters tracked by organisms, i.e., the concept that communities have no biologic reality, being merely statistical abstractions. The book is illustrated throughout with more than 400 photographs and drawings. It will be of interest to ethologists, evolutionists, parasitologists, paleontologists, and palaeobiologists at research and post-graduate levels.
In the days when dinosaurs dominated the earth, their marine counterparts—every bit as big and ferocious—reigned supreme in prehistoric seas. In this entrancing book, Richard Ellis, one of the world’s foremost writers on the denizens of the deep, takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. Working from the fossil record, Ellis explores the natural history of these fierce predators, speculates on their habits, and tells how they eventually became extinct—or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs, and mosasaurs who swam the ancient oceans—and who, according to some, may even still frequent the likes of Loch Ness. Picture if you will seventy-foot dragons with foot-long serrated teeth, or an animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to “a giant snake threaded through the body of a turtle.” At a length of nearly sixty feet, Mosasaurus hoffmanni boasted powerful jaws and teeth that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long—more than twice that of Tyrannosaurus Rex—with teeth to match. The first book about these amazing animals in nearly a century, Sea Dragons draws upon the most recent scientific research to vividly reconstruct their lives and habitats. Their fossils have been found all over the world—in Europe, Australia, Japan, and even Kansas—in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries, and competing theories that compose the fascinating world of vertebrate paleontology. Ellis also graces his text with a set of incomparable illustrations. Widely hailed as our foremost artist of marine natural history, he depicts vividly how these creatures probably appeared and, through these likenesses, invites us to speculate on their locomotion, their predatory habits, their very lifestyles. A genuine book of marvels and wonders, Sea Dragons will certainly stir one’s curiosity about our planet’s prehistoric past.
Despite their fame and reputation, dinosaurs represent only half the story of the Mesozoic Era. In Beast Companions: The Unsung Animals of the Dinosaurs' World, paleontologist John Foster explores the often-overlooked animals that coexisted with them. These ancient species, often equally remarkable as their dinosaur neighbors, can provide valuable insights into the biotic history of our planet. In some cases, these animals reveal just as much, if not more, about the extinct ecosystems of the time as the dinosaurs themselves. By drawing on a wealth of current and past discoveries, Foster embarks on a sweeping journey across 164 million years to visit the beast companions of the dinosaurs. Along the way, he examines fish, insects, the first frogs and salamanders, turtles, snakes and lizards, marine reptiles, crocodiles, pterosaurs, birds, mammals, and other animals of the Mesozoic Era. Beast Companions is a groundbreaking exploration of the story of these contemporaries of the dinosaurs that set the modern world in motion more than 200 million years ago
