abstract

• Both Pleistocene and Holocene vertebrate sites are reasonably common in Western North America, but having a Holocene site superposed on a Pleistocene one, with mixing of human artifacts and extinct horse, is rare. This, however, is the situation at Rancho Carabanchel in San Luis Potosi. Its most unique character lies in producing Equus specimens of Post-Pleistocene to Pre-Columbian age. C-14 dates obtained from this site have yielded ages ranging from 41000 to 930 years before the present (YBP). Six of them occur within a 3310 to 930 YBP time span. Materials on which the dates were obtained include carbon fragments, carbonized wood, snail shells and organic sediments. Most of these were found juxtaposed or else very closely associated with horse bones and/or teeth.
