For centuries, people had picked up huge bones in the ground and puzzled over their origins. In some parts of the world, they were thought to be the remains of legendary dragons, sea monsters, or Cyclopes. On the Greek island of Samos, the numerous large bones were thought to be the remains of Amazon warrior women who had died in battle. (We now know they are the remains of elephants, giraffes, antelopes, cattle, hyenas, and other mammals that were abundantly fossilized there.)
While gigantic vertebrae and other bones have been turning up for thousands of years to become woven into the legends of Native Americans and other cultures, the first scientifically recorded finds of what became known at first as “ceteosaurs”—and then sauropods—began in the 1830s. Like the evolution of the animals themselves, our human understanding of these dinosaurs took time to grow, often taking diversions until new finds and changes in scientific thinking happened to raise the curtain, each time a little bit more. <...>
The dinosaurs never expected it. Nor did any of the other organisms, from the tiniest bacteria to the great flying reptiles of the air that were thriving on a perfectly normal Cretaceous day 66 million years ago. One moment life, death, and renewal proceeded just as they had the day before, and the day before that, and the day before that, stretching back through millions upon millions of years. The next, our planet suffered the worst single day in the entire history of life on Earth <...>
If any proof were needed that the study of prehis-toric life is more than a matter of “old bones,” then this book provides it in ample measure. For here is a natural history of times past, featuring real creatures that lived, breathed, reproduced — then died forever. That they could be brought back to life in such convincing form is a credit to the painstaking scientific detective work of a team of paleontologists, writers and artists.
The ceratopista or horn-faced dinosaurs are exquisite creatures. They include large, exotic dinosaurs, the ceratopsids, with wondrous ornaments on their heads, including dazzling combinations of horns over the nose and eyes and lengthy frills behind the skull, often enhanced with rococo tracery and detailing. The ceratopsids are found only in western North America, although perhaps someday soon they will be found in Asia as well. Ceratopsians also include small, lithe protoceratopsids, shared equally between Asia and western North America. Protoceratopsids, which tend to be more tasteful and restrained in their adornments than ceratopsids, presumably include the ancestors of the ceratopsids. Recently admitted into the ceratopsian clan is the small Psittacosaurus from Asia, which is so generalized in its structure that it has neither horns nor a frill. <...>
It all started very suddenly, in the spring of 1955. I was reading magazines in my grandfather's house in New Jersey, and I found that magical Life cover story—"Dinosaurs." Fold-out, full-color pictures of heroic creatures. Allosaurus, Brontosaurus, Stegosaurus, Tyrannosaurus rex. I discovered an entire world, far, far away in time, that I could visit, whenever I wanted, via the creative labors of the paleontologists. And I made up my mind then and there that I would devote my life to the dinosaurs. Since I was in the fourth grade, my parents weren't alarmed at my vow.
The American Museum of Natural History, founded in 1869, is one of the world’s preeminent scientific, educational, and cultural institutions. The Museum encompasses 45 permanent exhibition halls, including those in the Rose Center for Earth and Space and the Hayden Planetarium, as well as galleries for temporary exhibitions. It is home to the Theodore Roosevelt Memorial, New York State’s official memorial to its 33rd governor and the nation’s 26th president, and a tribute to Roosevelt’s enduring legacy of conservation.
Reptiles are one of the most diverse groups of present- day vertebrates, with more than , described species of crocodylians, lepidosaurs, and turtles. If one adds birds (which are a clade of derived dinosaurs), this number more than doubles. Reptiles also have a rich and varied fossil rec ord spanning more than million years. They include the largest land animals of all time, and they repeatedly and successfully invaded the sea and took ¡ight.
Paleontology is the study of prehistoric life. It combines several fields, including geology (study of rocks), biology (study of living things), and chemistry (study of the basic building blocks of matter), to help piece together the evidence collected from fossils and the surrounding rocks. This evidence is usually incomplete because many important details are not preserved during the fossilization process. To make up for these gaps in information, paleontologists study fossils of similar species, as well as modern-day animals, to help them build a picture of prehistoric creatures and understand how they might have lived.
