Mammuthus from Linclon County and review of the mammoths from the Pleistocene of New Mexico
— Spencer G. Lucas and James A. Effinger

Mammoths were nearly ubiquitous during the Pleistocene in New Mexico, and published records and accessible museum specimens document 32 localities statewide. Three species of Mammuthus—M. meridionalis, M. imperator and M. columbi—are represented, but the vast majority of New Mexican mammoths are M. columbi. The oldest New Mexican mammoth is M. meridionalis from Tijeras Arroyo and is of early Irvingtonian age, 1.4-1.2 Ma. The youngest New Mexican mammoths for which some numerical dates can be inferred are from Blackwater Draw and Sandia Cave. These may be as young as 10,000 B.P.
