Abstract Fossils of the giant short-faced bear, Arctodus simus (Cope, 1879), have been recovered from over 100 localities in North America, extending from Mexico to Alaska and California to Virginia. Despite this large range, the species has never been recorded from the southeastern United States. The lesser short-faced bear, Arctodus pristinus Leidy, 1854 is well represented from this region, particularly Florida, but all known occurrences are late Pliocene – middle Pleistocene in age (about 2… 

The Largest Known Bear, Arctotherium angustidens, from the Early Pleistocene Pampean Region of Argentina: With a Discussion of Size and Diet Trends in Bears

It is suggested that the larger size and more carnivorous nature of A. angustidens, compared to later members of the genus, may reflect the relative lack of other large carnivores and abundance of herbivores in South America just after the Great American Biotic Interchange.

Giant short-faced bear (Arctodus simus) from late Wisconsinan deposits at Cowichan Head, Vancouver Island, British Columbia

A giant short-faced bear (Arctodus simus) ulna fragment was found at the base of exposed Quaternary sediments at Cowichan Head, southern Vancouver Island, British Columbia. In this paper, the ulna

Yucatán carnivorans shed light on the Great American Biotic Interchange

It is suggested that landscape and ecological changes caused by latest Pleistocene glaciation supported an interchange pulse that included A. wingei, P. troglodytes and Homo sapiens, and suggests a more complex history of these organisms in Middle America.

Dental caries in the fossil record: a window to the evolution of dietary plasticity in an extinct bear

The results suggest that the population of A. simus from RLB was more omnivorous than the highly carnivorous populations from the Northwest, and this dietary variation may be a consequence of different competitive pressures.

The Younger Dryas impact hypothesis: a cosmic catastrophe

In this paper we review the evidence for the Younger Dryas impact hypothesis (YDIH), which proposes that at ∼12.9k cal a BP North America, South America, Europe and the Middle East were subjected to

A morphological analysis of carnivoran ossicles from Rancho La Brea

The morphology of the mammalian middle ear—including the size, shape, and stiffness of individual ossicles—controls their vibrational response to sound and, is closely related to an animal's auditory

The hypothesis that giant short-faced bears of the genera Agriotherium and Arctodus were primarily carnivorous and preyed on large terrestrial mammals is examined. It is argued that the shape and

What size were Arctodus simus and Ursus spelaeus (Carnivora: Ursidae)?

Body masses of the giant short-faced bear and the cave bear were calculated with equations based on a long-bone dimensions:body mass proportion ratio ratio in extant carnivores, finding that large Arctodus specimens considerably exceeded even the largest extant ursids in mass.

Diet and Co-ecology of Pleistocene Short-Faced Bears and Brown Bears in Eastern Beringia

Carbon and nitrogen stable isotope analysis of fossil bone collagen reveals that Pleistocene short-faced bears of Beringia were highly carnivorous, while contemporaneous brown bears had highly variable diets that included varying amounts of terrestrial vegetation, salmon, and small amounts ofrestrial meat.

Dynamics of Pleistocene Population Extinctions in Beringian Brown Bears

Researchers studied genetic change in the brown bear, Ursus arctos, in eastern Beringia over the past 60,000 years using DNA preserved in permafrost remains to investigate the evolutionary impact of climatic and environmental changes associated with the last glaciation.
