Popis: We describe molars that represent the 1st fossils of Lemmiscus curtatus from Hagerman Fossil Beds National Monument (HAFO), Idaho. This species figures prominently in the biochronology of North American terrestrial deposits, so the possible ages of these records are discussed in detail. Most fossils from HAFO are from the middle Blancan (middle Pliocene), but these molars are likely from the Pleistocene or Holocene epoch, which is consistent with the temporal distribution of L. curtatus elsewhere.
