From the biggest teeth to the longest claws, SuperDinosaur uses jaw-dropping new lifelike images to bring you face-to-face with the most fearsome creatures that ever stalked the Earth.
Part of the series of award-winning, best-selling DK encyclopedias for children, this title has been completely revised to provide a comprehensive visual exploration of the entire range of prehistoric animal life.
The field of paleoclimatology relies on physical, chemical, and biological proxies of past climate changes that have been preserved in natural archives such as glacial ice, tree rings, sediments, corals, and speleothems.
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.
The vertebrate fossil record extends back more than 500 million years, and bonebeds-localized concentrations of the skeletal remains of vertebrate animals-help unlock the secrets of this long history.
Whether the fossil record should be read at face value or whether it presents a distorted view of the history of life is an argument seemingly as old as many fossils themselves.
As explorers and scientists have known for decades, the Neotropics harbor a fantastic array of our planet's mammalian diversity, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis.
Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines.
Nineteenth-century paleontologists boasted that, shown a single bone, they could identify or even reconstruct the extinct creature it came from with infallible certainty-"e;Show me the bone, and I will describe the animal!
Determining the precise timing for the evolutionary origin of groups of organisms has become increasingly important as scientists from diverse disciplines attempt to examine rates of anatomical or molecular evolution and correlate intrinsic biological events to extrinsic environmental events.
Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines.
"e;Peking Man,"e; a cave man once thought a great hunter who had first tamed fire, actually was a composite of the gnawed remains of some fifty women, children, and men unfortunate enough to have been the prey of the giant cave hyena.
Whether the fossil record should be read at face value or whether it presents a distorted view of the history of life is an argument seemingly as old as many fossils themselves.
This study provides a stimulating critique of contemporary evolutionary thought, analyzing the Modern Synthesis first developed by Theodosius Dobzhansky, Ernst Mayr, and George Gaylord Simpson.
Although researchers have long been aware that the species-typical architecture of the human mind is the product of our evolutionary history, it has only been in the last three decades that advances in such fields as evolutionary biology, cognitive psychology, and paleoanthropology have made the fact of our evolution illuminating.
The Pleistocene epoch or Ice Age, an extended period of advancing and retreating ice sheets, is characterized by striking climatic oscillations and sea level fluctuations.
The term "e;carbon cycle"e; is normally thought to mean those processes that govern the present-day transfer of carbon between life, the atmosphere, and the oceans.
