The book describes the increasingly highly resolved stratigraphy into which all available temporally significant data and applications are integrated. Extensive temporal coverage includes the Lancian part of the...

Toward the end of the Age of Dinosaurs, during a time known as the Late Cretaceous, a new type of giant predator appeared along the southern coasts of North America. It was a huge species of crocodylian called Deinosuchus. Neither a crocodile nor an alligator, it was an ancestor of both modern groups; it reached weights of many tons and it had some features unique to its own species. Average-sized individuals were bigger than the carnivorous dinosaurs with which they co-existed; the largest specimens were the size of a T-rex. King of the Crocodylians, the biography of these giant beasts,...

From 1907 to 1931 at Tendaguru, a remote site in present-day Tanzania, teams of German (and later British) paleontologists unearthed 220 tons of fossils, including the bones of a new dinosaur, one of the largest then known. For decades the mounted skeleton of this giant, Brachiosaurus, was the largest skeleton of a land animal on exhibit in the world. The dinosaur and other animal fossils found at Tendaguru form one of the cornerstones of our understanding of life in the Mesozoic era. Visited sporadically during the '30s and '40s, Tendaguru again became the site of scientific interest late...

This book gathers the findings of a number of studies on North American cave paleontology. Although not intended to be all-inclusive, Ice Age Cave Faunas of North America contains contributions that range from overviews of the significance of cave fossils to reports about new localities and studies of specific vertebrate groups. These essays describe how cave remains record the evolutionary patterns of organisms and their biogeography, how they can help reconstruct past ecosystems and climatic fluctuations, how they provide an important record of the evolution of modern ecosystems, and...

Over millions of years, Australia's unique biodiversity has produced a large cabinet of curiosities. Among the weirder members of this group were the Mihirungs, members of the now extinct family Dromornithidae. Made up of several genera of flightless birds-among them one of the very largest birds that ever lived-the dromornithids ranged from 60-kilogram beasts, 1.5 meters tall, to giants twice that size, weighing nearly half a metric ton. They were, by orders of magnitude, the largest "geese" that ever lived. One species was comparable in size to the Ele-phantbird of Madagascar and the...

Just 50,000 years ago the world was filled with fabulous creatures that are now forever gone. Australia's giant lizard, Megalania, was one of those. These frightful beasts could reach 19 feet in length and weigh as much as a polar bear. On their home turf they were top dog, and it was the rare animal that dared to challenge them. Dragons in the Dust tells the story of these amazing lizards and the world in which they lived. The book explores the Pleistocene, the time of the ice ages. While mammals ruled elsewhere, in Australia reptiles held their dominance. Large monitor lizards survive to...

The large, quadrupedal herbivores known as sauropods were widespread around the planet from the Jurassic to the end of the Cretaceous. With the longest necks and tails of all of the dinosaurs, some sauropods were 40 meters in length and weighed upwards of 100,000 kilograms, more than 20 tons. The popular image of these lumbering giants, placidly consuming ferns has been greatly revised in recent years. New discoveries and new theories about behavior and physiology have continued to enrich the study of these remarkable beasts. This book presents 21 new studies of the sauropods. The book is...

Call them "mudpuppies," "hellbenders," or "mud eels," salamanders are puzzling animals to most people. They come in forms that look like flattened fish with legs, like eels, like slimy lizards, or like lizards with toad-like skins. Their life history imitates the ancient evolutionary transition from aquatic to terrestrial vertebrates, though several groups remain permanently aquatic. Until now, no one has written about their ancient ancestors. Holman details the process of the identification and interpretation of the fossils. He presents a detailed systematic account of the known fossil...
