Taxonomic revision of Central Mexican mammoths in Paleoindian sites.
Central Mexican mammoth species taxonomy has been based on the quotient Molar length/Number of dental plates, which sorted three species, Mammuthus imperator, columbi and ?jeffersonii. New evidence from skull morphology sorts only two subspecies, M. columbi columbi and M. columbi felicis as being present during Paleoindian time.
