Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.

Sixty-six million years ago the dinosaurs were wiped from the face of the earth. Today a new generation of dinosaur hunters, armed with cutting-edge technology, is piecing together the complete story of how the dinosaurs created a hugely successful empire that lasted for around 150 million years.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark. And what we believed to be the history of our own species consisted of fantastic myths and fairy tales; fossils, known for millennia, were seen as the bones of dragons and other imagined creatures. How did we learn so much so quickly? Remarkable Creatures celebrates the pioneers who replaced our fancies with the even more remarkable real story of how our world evolved.

The spinosaurs – the controversial group that includes the largest land predator of all time, the awe-inspiring Spinosaurus – are brought to life in this cutting-edge review. The giant sail-backed carnivorous dinosaur Spinosaurus is one of the most famous of all dinosaurs; a staple of documentaries, books and video games, and the species that bested the mighty Tyrannosaurus rex in Jurassic Park III. The spinosaurs were some of the strangest predatory dinosaurs, combining a long low skull with powerfully clawed hands. Some species had huge sails over their backs, as well as fin-like tails.

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?

As soon as man discovered writing, he began engaging in historiography (historical writing and philosophy), but paleoanthropology only really began in the late 1800s. As archaeologists began finding bones in European caves of a human race that was very different than any race in the modern world, the study of paleoanthropology was born. The race of those early humans who were found in the European caves were later termed Neanderthals, and for quite some time, they were believed to have been the race from which many modern humans were directly descended.

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

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.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

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.

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.

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 ...

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.

The Third Edition of Evolution: The Grand Experiment is more than a book about evolution. It is a multimedia experience and includes eight video clips, 797 beautiful full color photographs, links to web pages, and 339 hyperlinked bibliography references for easy viewing. This book has the most accurate information about walking whales, walking seals and bat ancestors. The Grand Experiment now is the definitive source of information about walking whales with interviews with the scientists involved in the discovery of Rodhocetus, Ambulocetus, Pakicetus, Indohyus, SInonyx. Also this book has ...

Thirty thousand years ago our prehistoric ancestors painted perfect images of animals on walls of tortuous caves, most often without any light. How was this possible? Scholars and archaeologists have for centuries pored over these works of art, speculating and hoping to come away with the key to the mystery. David and Lefrre give us a new understanding of an art lost in time, revealing what had until recently remained unexplainable - the oldest enigma in humanity has been solved.

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 The Rise and Reign of the Mammals, Brusatte weaves together the history and evolution of our mammal forebears, iconic mammals such as the mammoths and sabre-toothed tigers of which we have all heard, and fascinating species that few of us are aware of. In this fascinating and ground-breaking book, Steve Brusatte tells their – and our – story.

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.

In the midst of the Industrial Revolution, an extraordinary group of scientists struggled to make sense of a mysterious, prehistoric world - a world that they had to piece together from the fossilized, fragmentary remains of animals no one had ever seen.
