C/C ratios of Pleistocene mummified remains from Beringia

Description :
Carbon stable isotope ratios of Beringian late Pleistocene mummified remains of bison, equids, mammoth, caribou, musk-ox, moose, woolly rhino, and other undeterminated species, found preserved in permafrost, indicate that these megaherbivores fed exclusively on C plants, and that C grasses were not differentially ingested by bison, as previously suggested. Paleoclimatic constraints probably prevented the formation of a warm season (C) guild during the later part of the growing season in the steppes of Beringia during the last glaciation.
