True stories of fossil-hunting adventures around the globe from “a world-class field scientist [and] a highly entertaining writer” (The American Scholar). Michael Novacek, a world-renowned paleontologist who has discovered important fossils on virtually every continent, is an authority on patterns of evolution and on the relationships among extinct and extant organisms. Time Traveler is his captivating account of how his boyhood enthusiasm for dinosaurs became a lifelong commitment to vanguard science. He takes us with him as he discovers fossils in his own backyard in Los Angeles, then goes looking for them in the high Andes, the black volcanic mountains of Yemen, and the incredibly rich fossil badlands of the Gobi Desert. Wherever Novacek goes, he searches for still-undiscovered evidence of what life was like on Earth millions of years ago. Along the way he has almost drowned, been stung by deadly scorpions, been held at gunpoint by a renegade army, and nearly choked in raging dust storms. Fieldwork is very demanding in a host of unusual, dramatic, sometimes hilarious ways, and Novacek writes of its alluring perils with affection and discernment. But in addition to being an enthralling adventure story, Time Traveler makes sense of many complex themes—about dinosaur evolution, continental drift, mass extinctions, new methods for understanding ancient environments, and the evolutionary secrets of DNA in fossil organisms. Includes photos and illustrations “A superb introduction to paleontology.” —Edward O. Wilson “An engaging book [that] gives us an excellent sense of the way paleontologists have arrived at their world-shaking conclusions.” —The New York Times Book Review “Novacek offers a spellbinding natural history of our planet, as well as the equally fascinating story of how he fell into the profession.” —Publishers Weekly
Living Dinosaurs offers a snapshot of our current understanding of the origin and evolution of birds. After slumbering for more than a century, avian palaeontology has been awakened by startling new discoveries on almost every continent. Controversies about whether dinosaurs had real feathers or whether birds were related to dinosaurs have been swept away and replaced by new and more difficult questions: How old is the avian lineage? How did birds learn to fly? Which birds survived the great extinction that ended the Mesozoic Era and how did the avian genome evolve? Answers to these questions may help us understand how the different kinds of living birds are related to one another and how they evolved into their current niches. More importantly, they may help us understand what we need to do to help them survive the dramatic impacts of human activity on the planet.
Paleontology is one of the most visible yet most misunderstood fields of science. Children dream of becoming paleontologists when they grow up. Museum visitors flock to exhibits on dinosaurs and other prehistoric animals. The media reports on fossil discoveries and new clues to mass extinctions. Nonetheless, misconceptions abound: paleontologists are assumed only to be interested in dinosaurs, and they are all too often imagined as bearded white men in battered cowboy hats. Roy Plotnick provides a behind-the-scenes look at paleontology as it exists today in all its complexity. He explores the field’s aims, methods, and possibilities, with an emphasis on the compelling personal stories of the scientists who have made it a career. Paleontologists study the entire history of life on Earth; they do not only use hammers and chisels to unearth fossils but are just as likely to work with cutting-edge computing technology. Plotnick presents the big questions about life’s history that drive paleontological research and shows why knowledge of Earth’s past is essential to understanding present-day environmental crises. He introduces readers to the diverse group of people of all genders, races, and international backgrounds who make up the twenty-first-century paleontology community, foregrounding their perspectives and firsthand narratives. He also frankly discusses the many challenges that face the profession, with key takeaways for aspiring scientists. Candid and comprehensive, Explorers of Deep Time is essential reading for anyone curious about the everyday work of real-life paleontologists.
Highlighting the most important topics, issues, questions and debates, these two volumes offer full coverage of major subthemes and subfields within the discipline of anthropology.
The aim of the book is to present original and though-provoking essays in human paleontology and prehistory, which are at the forefront of human evolutionary research, in honor of Professor Yoel Rak (a leading scholar in paleoanthropology).​ ​The volume presents a collection of original papers contributed by many of Yoel's friends and colleagues from all over the globe. Contributions from experts around the globe fall roughly into three broad categories: Reflections on some of the broad theoretical questions of evolution, and especially about human evolution; the early hominins, with special emphasis on Australopithecus afarensis and Paranthropus; and the Neanderthals, that contentious group of our closest extinct relatives. Within and across these categories, nearly every paper addresses combinations of methodological, analytical and theoretical questions that are pertinent to the whole human evolutionary time span. This book will appeal most to scholars and advanced students in paleoanthropology, human paleontology and prehistoric archaeology.
"Bubbles over with the joy of scientific discovery as he shares his natural enthusiasm for the blend of sleuthing and imagination."—Publishers Weekly, starred review What if we woke up one morning all of the dinosaur bones in the world were gone? How would we know these iconic animals had a165-million year history on earth, and had adapted to all land-based environments from pole to pole? What clues would be left to discern not only their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, whether they lived underground, climbed trees, or went for a swim?Welcome to the world of ichnology, the study of traces and trace fossils – such as tracks, trails, burrows, nests, toothmarks, and other vestiges of behavior – and how through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the 21st century reader.
