CONTRIBUTIONS FROM THE MUSEUM OF PALEONTOLOGY
-The Shelton Mastodon Site (Oakland County, Michigan) was the subject of a five-year multidisciplinary study and yielded late Wisconsinan remains of algae, plants, invertebrates and vertebrates. The…
Out of America: Ancient DNA Evidence for a New World Origin of Late Quaternary Woolly Mammoths
A 130,000-year-old archaeological site in southern California, USA.
These findings confirm the presence of an unidentified species of Homo at the CM site during the last interglacial period (MIS 5e; early late Pleistocene), indicating that humans with manual dexterity and the experiential knowledge to use hammerstones and anvils processed mastodon limb bones for marrow extraction and/or raw material for tool production.
Oxygen isotope variation in the tusks of extinct proboscideans: A measure of season of death and seasonality
Centimetre-scale laminae in tusk and molar dentine of late Pleistocene mastodonts and mammoths have been interpreted as annual growth bands produced, in part, by seasonal variation in growth rate. To…
Crocodilian scatology, microvertebrate concentrations, and enamel-less teeth
- D. Fisher
- Geography, Environmental Science
- 1 April 1981
It has been suggested that certain fossil assemblages consisting of disarticulated and broken remains of small to medium-sized vertebrates ("microvertebrate concentrations") may be accumulations of…
Regulation of Dental Enamel Shape and Hardness
The growth parameters that determine the shape of the enamel crown as well as the mechanisms of enamel appositional growth and maturation are reviewed.
STRATOCLADISTIC ANALYSIS OF PALEOCENE CARPOLESTIDAE (MAMMALIA, PLESIADAPIFORMES) WITH DESCRIPTION OF A NEW LATE TIFFANIAN GENUS
Abstract “Carpodaptes” jepseni is a morphologic intermediate between Carpodaptes and Carpolestes, with the number and position of cusps on p4 more consistent with placement in Carpodaptes but…
Pre-Clovis occupation 14,550 years ago at the Page-Ladson site, Florida, and the peopling of the Americas
Sporormiella and other proxy evidence from the sediments indicate that hunter-gatherers along the Gulf Coastal Plain coexisted with and utilized megafauna for ~2000 years before these animals became extinct at ~12,600 cal yr B.P.
Complete Columbian mammoth mitogenome suggests interbreeding with woolly mammoths
Though limited, the data suggest that the two species interbred at some point in their evolutionary histories, and the use of next-generation sequencing technologies holds promise in obtaining such data, even from non-cave, non-permafrost Pleistocene depositional contexts.
Evolution of High Tooth Replacement Rates in Sauropod Dinosaurs
- M. D’Emic, John A. Whitlock, Kathlyn M. Smith, D. Fisher, JEFFREY A. Wilson
- GeographyPloS one
- 17 July 2013
Differences in tooth replacement rate among sauropodomorphs likely reflect disparate feeding strategies and/or food choices, which would have facilitated the coexistence of these gigantic herbivores in one ecosystem.
