The disappearance of many North American megafauna at the end of the Pleistocene is a
contentious topic. While the proposed causes for megafaunal extinction are varied, most …

In 2002, we assessed all sites known to us that had been suggested to provide evidence for
the association of Clovis-era archaeological material with the remains of extinct Pleistocene …

The saber-toothed cat, Smilodon fatalis, and American lion, Panthera atrox, were among the
largest terrestrial carnivores that lived during the Pleistocene, going extinct along with other …

Large, carnivorous mammals often break their teeth, probably as a result of tooth to bone
contact that occurs when carcasses are consumed more fully, a behaviour likely to occur …

Australia has been cited as a weak link in anthropogenic models of megafauna extinction,
but recent work suggests instead that the evidence for rapid extinction shortly after human …

Rigorously studied and dated Late Quaternary paleoenvironmental reconstructions from
Ranch La Brea (RLB) and the Los Angeles Basin are scarce. Here, we use data from AMS …

The carnivores preserved in the late Pleistocene Rancho La Brea tar seep deposits display
a remarkably high incidence of teeth broken in life as compared with modern species. In a …

A novel protocol to purify bone collagen for radiocarbon dating and stable isotope ratio
analysis from asphalt-impregnated skeletal remains stored in the George C. Page Museum …

Accurate radiocarbon dating and stable isotope ratio analysis of bone from Rancho La Brea
and other tar seep sites is complicated by the necessity for the efficient and complete …

The role of Quaternary glacial–interglacial intervals in shaping the diversity and distribution
of Neotropical species has been the focus of considerable research. The Neotropics sustain …
