Picture yourself in the Cretaceous period. It’s a sunny afternoon in the Hell Creek of ancient Montana 66 million years ago. A Triceratops horridus ambles along the edge of the forest. In a matter of hours, everything here will be wiped away. Lush verdure will be replaced with fire. Tyrannosaurus rex will be toppled from their throne, along with every other species of non-avian dinosaur no matter their size, diet, or disposition. They just don’t know it yet.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals.

Hace unos 4.000 millones de años apareció la vida en la Tierra. ¿Cuál es la historia de su evolución? ¿Era inevitable la vida? ¿Y la raza humana? ¿La habría habitado algún otro ser inteligente, si no hubiera habido humanos? ¿Qué patrones usa el mecanismo evolutivo? ¿La evolución avanza hacia adelante como una flecha?

Fifty thousand years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements.

This dynamic chronicle of the race to find the "missing links" between humans and apes transports readers into the highly competitive world of fossil hunting and into the lives of the ambitious scientists intent on pinpointing the dawn of humankind. The quest to find where and when the earliest human ancestors first appeared is one of the most exciting and challenging of all scientific pursuits.

Blending fiction with fact, 50 Dinosaur Tales imagines the way 50 newly described dinosaurs from the Triassic, Jurassic, and Cretaceous lived in their natural habitats. Also included is a list of fun facts for each dinosaur story and facts about 108 additional dinosaurs.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

Dinosaurs, with their awe-inspiring size, terrifying claws and teeth, and otherworldly abilities, occupy a sacred place in our childhoods. They loom over museum halls, thunder through movies, and are a fundamental part of our collective imagination. In My Beloved Brontosaurus, the dinosaur fanatic Brian Switek enriches the childlike sense of wonder these amazing creatures instill in us. Investigating the latest discoveries in paleontology, he breathes new life into old bones.

Although dinosaur fossils were first found in England, a series of dramatic discoveries during the late 1800s turned North America into a world center for vertebrate paleontology. At the same time, the United States emerged as the world’s largest industrial economy, and creatures like tyrannosaurus, brontosaurus, and triceratops became emblems of American capitalism. Large, fierce, and spectacular, American dinosaurs dominated the popular imagination, making front-page headlines and appearing in feature films.

Big Bone Lick: The Cradle of American Paleontology recounts the rich history of the fossil site that gave the world the first evidence of the extinction of several mammalian species, including the American mastodon. Big Bone Lick has played many roles: nutrient source, hallowed ground, salt mine, health spa, and a rich trove of wonders. Stanley Hedeen presents a comprehensive narrative of Big Bone Lick from its geological formation forward, explaining why the site attracted animals, regional tribespeople, European explorers and scientists, and eventually American pioneers.

In 1938 the discovery of a large, unusual fish turned the scientific community on end. Dubbed a living fossil, the discovery of a coelacanth in South Africa shocked scientists around the world who thought this type of fish had died out millions of years prior during the process of evolution. Living fossils are organisms found preserved in the fossil record, which still exist in similar form today. If the core concepts of the theory of evolution presuppose change over time, then how can these living fossils exist for millions of years remaining virtually unchanged? Whether a shark, leaf, or ...

In 1990, Peter Larson, with his team of commercial fossil hunters from the Black Hills Institute, discovered the most complete Tyrannosaurus Rex specimen in history. He dubbed it "Sue" after the field paleontologist who first saw it sticking out of a sandstone cliff on the ranch of Maurice Williams, a Cheyenne River Sioux Tribe member in South Dakota's badlands. Because the skelton was 90% complete, its study promised to yield up priceless information on the life and habits of the T Rex.

Los dinosaurios, las criaturas más formidables de la Tierra, se desvanecieron hace ya sesenta y seis millones de años, pero siguen siendo uno de los misterios más intrigantes de todos los tiempos. En Auge y caída de los dinosaurios, el paleontólogo Steve Brusatte repasa la evolución de estos extraordinarios seres mientras nos hace partícipes de sus apasionantes expediciones alrededor del mundo y sus recientes descubrimientos, que ponen en entredicho todo cuanto creíamos saber sobre la evolución de los dinosaurios.

Otros mundos devuelve a la vida dieciséis ecosistemas de un pasado inimaginablemente remoto y nos muestra continentes en movimiento, arrecifes de cristal, hongos de tres metros de altura, pingüinos gigantes, reptiles emplumados y muchas otras criaturas asombrosas de un atractivo casi mitológico. A medida que viajamos hacia atrás en el tiempo, redescubrimos nuestro propio hogar de formas irreconocibles, y nos sobrecogen los ecosistemas que se transforman y los devastadores escenarios que han causado el fin de incontables especies.

A thrilling scientific investigation and the portrait of an extraordinary genius, The Seashell on the Mountaintop gives us new insight into our planet, revealing how we learned to read the story told to us by the Earth itself, written in rock and stone.

Et si nous nous étions fourvoyés sur ce que fut l’homme de Néandertal ? Dans un véritable récit de voyage, Ludovic Slimak retrace son parcours de chercheur et nous entraîne dans une étonnante enquête archéologique. Pendant trente ans, il a inlassablement traqué ce qu’il appelle la créature. Créature, comme l’un de ces êtres qu’on apercevrait de loin, dans les brumes, sans vraiment savoir ce qu’il est, sans vraiment savoir le qualifier.

In his new book The Strange Case of the Rickety Cossack, human paleoanthropologist Ian Tattersall argues that a long tradition of "human exceptionalism" in paleoanthropology has distorted the picture of human evolution. Drawing partly on his own career - from young scientist in awe of his elders to crotchety elder statesman - Tattersall offers an idiosyncratic look at the competitive world of paleoanthropology.
