Toward the end of the Pleistocene, North America lost some 35 genera of mammals. It has long been assumed that all or virtually all of the extinctions occurred between 12,000 and 10,000 years ago, but detailed analyses of the radiocarbon chronology provide little support for this assumption, which seems to have been widely accepted because of the kinds of explanations felt most likely to account for the extinctions in the first place. Approaches that attribute the losses to human predation… 

Synchronous extinction of North America's Pleistocene mammals

The extinction chronology of North American Pleistocene mammals can be characterized as a synchronous event that took place 12,000–10,000 radiocarbon years B.P.

Clovis Hunting and Large Mammal Extinction: A Critical Review of the Evidence

The North American archaeological phenomenon known as Clovis is famous for the fact that a number of sites that contain diagnostic Clovis artifacts also contain the remains of mammoth and perhaps

Late Quaternary Extinctions: State of the Debate

Results from recent studies suggest that humans precipitated extinction in many parts of the globe through combined direct (hunting) and perhaps indirect (competition, habitat alteration) impacts, but that the timing and geography of extinction might have been different and the worldwide magnitude less, had not climatic change coincided with human impacts in many places.

Prehistoric Extinctions on Islands and Continents

Geological extinction of a continental megafauna of Holarctic mammoths, American ground sloths, and Australian diprotodonts, to name a few mammalian examples, rivals pulsing ice sheets and

Pleistocene extinctions: the pivotal role of megaherbivores

The elimination of megaherbivore influence is the major factor differentiating habitat changes at the end of the terminal Pleistocene glaciation from those occurring at previous glacial-interglacial transitions.

The Biogeographic History of Small Mammals in the Great Basin: Observations on the Last 20,000 Years

Evidence from archaeological and paleontological sites meets key predictions drawn from J. H. Brown's argument that boreal mammals colonized the Great Basin during the Pleistocene, only to become

Climatic implications of Late Pleistocene and Holocene faunal associations in Australia

Late Pleistocene mammalian faunas of Australia contain many extant taxa that indicate more mesic conditions. The presence of many disharmonious pairs of taxa in these faunas implies that the

Faunal Dynamics of Pleistocene Mammals

Tee Age mammals, the dramatis personae of this review, can be divided into three groups-megafauna, microfauna, and humans-each of which plays a fundamentally different role. Surely the most

This volume of papers resulted from a symposium held at the 1980 Plains Conference at the University of Iowa. A unifying theme stressed by the editors is that paleoenvironmental reconstructions
