چکیده انگلیسی
Average δ13C values of the aragonite shells of the fossil Vallonia range from â7.3 to â6.0â° among different archaeological levels and are not as negative as modern values. This suggests that the proportion of C4 vegetation at the Folsom site approximately 10,500 14C yr B.P. was greater than at present; a result which is consistent with other evidence for higher proportions of C4 plants in the region at that time.
