      For fossil mammal faunas of the Rocky Mountain region of North America, African transfer functions fail, but Australian transfer functions predict paleoprecipitation back to the Cretaceous–Tertiary boundary (66 Ma). Furthermore, modern mallee soils investigated in this study closely match Cretaceous to Eocene paleosols of the Rocky Mountains. "Cenozoic Mammals of Africa does not disappoint: here is a magisterial volume of nearly pages of densely packed information authored by many of the leading scholars of our time. The book provides excellent summaries of the geological, geographic, climatic, ecological and chronological settings in which the mammals of Africa have evolved.

      The North American Land-Mammal Age system was formalized in as a series of provincial land-mammal ages. The system was the standard for correlations in the terrestrial Cenozoic record of North America and was the source for similar time scales dealing with other continents. The system was revised into a formal chronostratigraphic system.   The modern effect of climate on plants and animals is well documented. Some have cautioned against assigning climate a direct role in Cenozoic land mammal faunal changes. We illustrate 3 episodes of significant mammalian reorganization in the Eocene of North America that are considered direct responses to dramatic climatic events. The first episode occurred during the Paleocene–Eocene.

The Giant Mammals of the Eocene, Oligocene, and Miocene Epochs. The Eocene epoch, from 56 to 34 million years ago, witnessed the first plus-sized herbivorous success of Coryphodon, a half-ton plant-eater with a tiny, dinosaur-sized brain, can be inferred by its wide distribution across early Eocene North America and the megafauna of the Eocene epoch.

During the American megafaunal extinction event aro years ago, 90 genera of mammals weighing over 44 kilograms became extinct. The Late Pleistocene fauna in North America included giant sloths, short-faced bears, several species of tapirs, peccaries (including the long-nosed and flat-headed peccaries), the American lion, giant tortoises, Miracinonyx ("American cheetahs", not true.

At around 55 Ma metamorphosed sedimentary and volcanic rocks of the Pacific Rim Terrane were forced a few tens of kilometres. These groups apparently arrived in South America from North America, perhaps in the latter part of the Cretaceous before the beginning of the Cenozoic.

These faunas also contain other elements from North America and from the ancient Mesozoic mammalian fauna, which then become extinct in South America through competition with the more advanced.

During the latter part of the Cenozoic Era—from about 50 million years ago to the end of the last Ice Age—prehistoric mammals were significantly bigger (and stranger) than their modern counterparts.

On the following slides, you'll find pictures and detailed profiles of over 80 different giant mammals and megafauna that ruled the earth after the dinosaurs.inafforded the American bases for Osborn's Cenozoic Mammal Horizons of Western North America, published inin which for the first time the succession of the mammalian life of the New and Old Worlds is closely compared.

In the meantime increasingly accurate field methods, especially.The Phanerozoic Eon is divided into three great eras - Paleozoic, Mesozoic and Cenozoic Eras. Most geological books and articles concentrate upon this last 10% of Earth history because the record is the most fresh and abundant.

During the Paleozoic Era multitudes of life arose and died; Mesozoic time was the age of the dinosaurs, and Cenozoic time is the age of mammals.
