| ABSTRACT: | A lower second molar of a Jeffersonian mammoth (Mammuthus jeffersonii) from northern Illinois provides the first reliable record of this species from the state. A radiocarbon date of 11,170 ± 140 14C yr B.P. on spruce (Picea) wood from the site suggests an age of late Pleistocene for the mammoth specimen. Although this is the first description of M. jeffersonii from Illinois, the locality is within the expected range of this taxon. The restricted geographical distribution of M. jeffersonii in the upper Midwest during the late Pleistocene may indicate a close association between this species and spruce-dominated open forests.
