During this fantastically illustrated normal background that hyperlinks extinct greater pussycat species with these nonetheless in lifestyles, collaborators Alan Turner and Mauricio Anton weave jointly the facts of contemporary pussycat habit with that of the fossil list. Turner's transparent, insightful prose and Anton's masterly illustrations mix to provide experts and newbies alike a correct and available advisor to the evolution of cats.
This publication offers a finished remedy of the entire Pleistocene species in Europe, labeled in line with sleek taxonomic ideas. for every species there's a description of its descent and migration historical past, its variety, and its mode of existence. the 1st model of this ebook was once a semipopular paperback within the Swedish Aldus sequence.
The distinguished Solnhofen limestone is likely one of the most vital fossil deposits due to its awesome variety of organisms, many exquisitely preserved. This ebook illustrates the various marine and terrestrial creatures and vegetation, buried a hundred and fifty million years in the past in tender lagoonal muds, to supply a different glimpse into the real range of Jurassic existence.
Sixty-five million years in the past, a comet or asteroid better than Mount Everest slammed into the Earth, inducing an explosion comparable to the detonation of 100 million hydrogen bombs. Vaporized detritus blasted throughout the surroundings upon influence, falling again to Earth all over the world. Disastrous environmental effects ensued: a tremendous tsunami, continent-scale wildfires, darkness, and chilly, by means of sweltering greenhouse warmth.

During Solutrean times there may have been many accidental and purposeful trips back and forth between southwest Europe and North America. As the ice age waned, the sea ice edge and its associated resources retreated northward, the glaciers melted, and the sea level rose, flooding the continental shelf and increasing the distances across open water. At the same time, the environment of the European mainland improved and the need for a maritime focus lessened. It was no longer necessary, or attractive, to ply the North Atlantic.
Today, after nearly sixty years of research, there is still no archaeological proof that Clovis peoples or anyone before them passed between the glaciers while moving from Asia to the plains of North America. In spite of this lack of evidence, the widely held perception that all Native Americans are closely related to northeast Asians had still convinced many researchers that the mystery of Clovis origins would be uncovered in Siberia. They thought that detailed information about that vast area had been just beyond their grasp, but with the opening up of China for research and the later collapse of the Soviet Union it appeared that this major piece of the puzzle might be forthcoming.
But they found scant evidence of Clovis in private collections—and the farther north they went, the fewer Clovis-like artifacts they found. They did not achieve their goal of proving the peopling of the Americas by Asians, but they did make a major contribution to the knowledge of the northern plains’ prehistory. Since Sable’s early find in northern Alaska and Wormington and Forbis’s Alberta survey, countless other explorers have sought evidence for the first Americans in the corridor, but the few datable fluted points recovered are no older than the Clovis artifacts they were imagined to precede.
