Photograph of a mammoth tooth, with scale bar. In this instance, “mammoth” refers both to the size and the species of the tooth. It is large and brown, with cracks and many roots.

Photograph of a mammoth tooth. Discovered in a lake in Bering Land Bridge National Preserve by NPS aquatic ecologist Amy Larsen and pilot Eric Sieh (Rasic 2012), this mammoth tooth was radiometrically dated using carbon-14 isotopes, producing an age of 12,330 radiocarbon years before present. A semi-articulated mammoth humerus and ulna, two mammoth vertebra, a mammoth rib fragment, and possible mammoth cranial bones were discovered in proximity to the tooth. Because these bones were found clustered together, they likely originated from a single individual. Finds of multiple mammoth bones from the same skeleton are relatively uncommon in Alaska, making this one of the more complete mammoth skeletons known from the state.
