Herbivore tooth oxygen isotope compositions: Effects of diet and physiology
-The applicability of rapid and precise laser probe analysis of tooth enamel for 6 ~O has been verified, and the method has been applied to different modern herbivores in East Africa. Sampling and pretreatment procedures involve initial bleaching and grinding of enamel to <75 /~m, and elimination of adsorbed water and organic compounds with BrFs. Typical analytical reproducibilities for 0 .5-2 ...
متن کاملLate Pleistocene/Early Holocene Migratory Behavior of Ungulates Using Isotopic Analysis of Tooth Enamel and Its Effects on Forager Mobility
Zooarchaeological and paleoecological investigations have traditionally been unable to reconstruct the ethology of herd animals, which likely had a significant influence on the mobility and subsistence strategies of prehistoric humans. In this paper, we reconstruct the migratory behavior of red deer (Cervus elaphus) and caprids at the Pleistocene-Holocene transition in the northeastern Adriatic...
متن کاملVariability in oxygen isotope compositions of herbivore teeth: reflections of seasonality or developmental physiology?
Oxygen isotope compositions of herbivore tooth enamel from two areas in Kenya were measured using a laser Ž . fluorination approach. Isotope heterogeneity was found within four sets of teeth in the jaws of different individuals ;2‰ , Ž . as well as within individual teeth. The rear molar M3 of a zebra shows a 1.4‰ variability, whereas, the middle and rear Ž . Ž . molars M2 and M3 of a gazelle s...
متن کاملDietary and environmental reconstruction with stable isotope analyses of herbivore tooth enamel from the Miocene locality of Fort Ternan, Kenya.
Tooth enamel of nine Middle Miocene mammalian herbivores from Fort Ternan, Kenya, was analyzed for delta 13C and delta 18O. The delta 18O values of the tooth enamel compared with pedogenic and diagenetic carbonate confirm the use of stable isotope analysis of fossil tooth enamel as a paleoenvironmental indicator. Furthermore, the delta 18O of tooth enamel indicates differences in water sources ...
متن کاملLand use and mobility during the Neolithic in Wales explored using isotope analysis of tooth enamel
OBJECTIVES The nature of land use and mobility during the transition to agriculture has often been debated. Here, we use isotope analysis of tooth enamel from human populations buried in two different Neolithic burial monuments, Penywyrlod and Ty Isaf, in south-east Wales, to examine patterns of land use and to evaluate where individuals obtained their childhood diet. MATERIALS AND METHODS We...
