Abstract. We report the first radiocarbon ages on vertebrate fossils from Labor-of-Love Cave, White Pine County, Nevada, based on purified collagen in teeth and bone, as well as a description of the
Late Pleistocene giant short‐faced bears, mammoths, and large carcass scavenging in the Saltville Valley of Virginia, USA
The Saltville Valley of southwestern Virginia contains an abundance of extinct Late Pleistocene megafauna. Recent excavations in the valley produced two particularly notable discoveries, the remains
Biogeographic problem-solving reveals the Late Pleistocene translocation of a short-faced bear to the California Channel Islands
While representing just a single specimen, the combination of techniques opened a window into the behavior of an enigmatic species, suggesting that A. simus was a wide-ranging scavenger utilizing terrestrial and marine carcasses.
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.
It is suggested that two distinct sizes, presumably representing malds and fanales, are available to study within an early Irvingtonian vertebrate'locality within a marine shell'bedj.
High-elevation late Pleistocene (MIS 6–5) vertebrate faunas from the Ziegler Reservoir fossil site, Snowmass Village, Colorado
Was the Giant Short-Faced Bear a Hyper-Scavenger? A New Approach to the Dietary Study of Ursids Using Dental Microwear Textures
Compatibility of dental microwear textures of first and second lower molars with diet in extant ursids is assessed to evaluate the hypothesis that the Pleistocene giant short-faced bear, Arctodus simus, was a bone consumer and hyper-scavenger at Rancho La Brea, California, USA.
