"Describes how the Pterodactyl and other pterosaurs were discovered, how paleontologists study their bones, and what the fossil evidence tells us about these ancient flying lizards"--Provided by publisher.

Ecological competition began as slow arms races. Predators evolved to hunt. Prey evolved to defend themselves. Each improvement was small, barely shifting the odds of survival. Nature remained in equilibrium. Until the dawn of humanity. When our ancestors developed the unique ability to think up new devices and behaviors, humanity became able to overcome nature's defenses far more quickly than natural selection could respond. Humankind spread out...

The preparation of this book was motivated by a longfelt need for a concise yet fairly comprehensive textbook of paleobotany for use in American colleges and universities. Although separate courses in paleobotany are not offered in many institutions, fossil plants are frequently treated in regular courses in botany and paleontology. In these courses both student and instructor are often compelled to resort to widely scattered publications, which are...

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...

This book is a picture guide to fossil plants and a few fossil marine organisms found in close association with the coal measures in Southwestern Virginia. The fossils are, sorted by groups, and located as to coal seam horizon and geographic location. Short descriptions of each group of plant types are, provided. This publication has been, designed with the armature ("rock hound") as well as a virtual guide for the more advanced collectors. There...

Las respuestas de la ciencia a las preguntas fundamentales sobre el origen de la vida y el origen del ser humano. Desde las primeras bacterias -3.800 millones de años- y los primeros organismos, plantas y vertebrados, hasta la conquista de la tierra, la era de los dinosaurios, los mamíferos y la aparición de los homínidos en el mioceno hace 7 millones de años. ¿Son primas las ballenas y las vacas?, ¿Cómo eran las primeras formas de vida?,...

Mammoths, Sabertooths, and Hominids takes us on a journey through 65 million years, from the aftermath of the extinction of the dinosaurs to the glacial climax of the Pleistocene epoch; from the rain forests of the Paleocene and the Eocene, with their lemur-like primates, to the harsh landscape of the Pleistocene Steppes, home to the woolly mammoth. It is also a journey through space, following the migrations of mammal species that evolved on other...

Four years after the destruction of Isla Nublar, dinosaurs now live and hunt alongside humans all over the world. This fragile balance will reshape the future and determine, once and for all, whether human beings are to remain the apex predators on a planet they now share with history's most fearsome creatures in a new era.

Chronicles the rapid evolution of thousands of species of mammals that took place during the Cenozoic Era and explains how this evolution led to the world as it is today.
