Abstract

Lower dentitions essentially identical to the holotype of Marmota sawrockensis Hibbard, 1964, are described from the Santee and Devils Nest Airstrip local faunas (very late Hemphillian) in Knox County, Nebraska. These, along with newly-collected upper cheekteetb (previously unknown for tbis taxon), show that the species should be transferred to the genus Paenemarmota Hibbard and Schultz, 1948. P. sawrockensis appears to be structurally intermediate between ?Marmota nevadensis of the early Hemphillian and P. barbouri, a latest Hemphillian and Blancan species.
