Mammals first appeared during the Cenozoic era. Not. Mammals, which had been small and few during the Mesozoic, became more diverse. New mammal species evolved and were able to live in areas and eat foods that had been used by dinosaurs during the Mesozoic. Grass evolved and was well adapted to the cooler climates of the late Cenozoic.

    This book is devoted exclusively to the Cenozoic era in southern Africa. The authors explore a variety of themes within this time frame, beginning with the evolution of the major landforms of the subcontinent: the old landscapes of southern Africa are host to a wide variety of deposits of differing ages.

Continental eolian source regions beginning during the late Pliocene. INTRODUCTION The equatorial oceans are greatly influenced by changes in Earth's climate system. The biology, chemistry, and sedimentation in this region are closely related to changes in oceanic circulation, which varies primarily in response to atmospheric circulation.

There exists a reasonable geologic record of atmospheric circulation, based on information extracted from eolian dust preserved in deep-sea sediments, that extends back to the late Cretaceous in the northern hemisphere and to the late Oligocene in the southern by: 5.

ing the Cenozoic, at least in the polar regions. However, the degree of cooling was only expressed in qualitative terms.

It was not until late in the latter half of the 20th century that quantitative methods were developed for es-timating paleotemperatures.

The detailed ideas of cool-ing during the Cenozoic are based on oxygen isotope ra. Eolian dust deposition is intimately related to atmospheric circulation and environmental setting of the source region, and therefore is an invaluable tool for studying the evolutionary history of.

From matching of a Phanerozoic curve of atmospheric CO 2 concentration, based on estimates of deposition of carbonate on the continents, with a sub‐parallel curve for abundance of continental volcanic rocks, Budyko and Ronov concluded that global climate changes are related to the variable output of CO 2 from volcanic activity.

Lakes in one form or another have characterized the western Mojave Desert since at least Miocene time. The most recent of these, Lake Thompson, developed in the late Pleistocene, when it covered as much as km 2 and rose to at least m above sea level.

FEAKINS AND PETER B. DEMENOCAL The last 65 Ma of Earth’s history, the Cenozoic, has been a time characterized by significant climate change. Major global changes included massive tectonic reorganization, a reduction in atmospheric pCO 2 (Pagani et al., ; Pearson.
