    The Perspective editorial by Braje, T., T. D. Dillehay, J. M. Erlandson, S. M. Fitzpatrick, D. K. Grayson, V. T. Holliday, R. L. Kelly, R. G. Klein, D. J. Meltzer, and T. C. Rick (2017. “Were Hominins in California ∼130,000 Years Ago?” PaleoAmerica 3 (3): 200–202) takes issue with our argument [Holen, S. R., T. A. Deméré, D. C. Fisher, R. Fullagar, J. B. Paces, G. T.

  • Broken Bones and Hammerstones at the Cerutti Mastodon Site

    Steven R Holen, Thomas A Deméré et al.ARTICLEPaleoAmerica2017Cited by: 3References: 6

    Haynes [2017 “The Cerutti Mastodon.” PaleoAmerica 3 (3): 196–199] criticizes numerous aspects of our analysis of the Cerutti Mastodon (CM) site, but central among his points is the claim that heavy equipment broke the bones and stones that we interpret as evidence of ancient human activity. This notion can be discounted primarily because most of the relevant CM fragments were found coated in thick crusts of pedogenic carbonate clearly showing tha…

  • Spatial Response of Mammals to Late Quaternary Environmental Fluctuations

    Open AccessRussell W Graham, 一穂 高橋 et al.ARTICLEScience1996

    Analyses of fossil mammal faunas from 2945 localities in the United States demonstrate that the geographic ranges of individual species shifted at different times, in different directions, and at different rates in response to late Quaternary environmental fluctuations. The geographic pattern of faunal provinces was similar for the late Pleistocene and late Holocene, but differing environmental gradients resulted in dissimilar species composition…

  • Seasonal Migration of Bison Antiquus from Rancho La Brea, California

    Open AccessGeorge T Jefferson, Judith L GoldinARTICLEQuaternary Research1989

    Evidence for annual seasonal migration of extinct Bison antiquus in the late Pleistocene fossil assemblage from Rancho La Brea, California, is demonstrated for the first time. The maturation of individuals from the B. antiquus sample was analyzed using the cheek tooth eruption sequence and occlusal wear patterns in juvenile and young adult inferior dentitions. Individual age of the specimens was established by comparison with wear stages observed…

  • New Source of Dietary Data for Extinct Herbivores

    Open AccessWilliam A Akersten, Theresea M Foppe et al.ARTICLEQuaternary Research1988

    The teeth of many large herbivores contain “pockets” (fossettes, fossettids, etc.) which entrap impacted samples of food (dental boluses) during mastication. These do not preserve well in most fossil deposits, but at Rancho La Brea, paleobotanical remains survive essentially intact and dental boluses from late Pleistocene forms are amenable to microhistological analysis. Of the identifiable bolus contents, those from Bison antiquus averaged 87% n…
