Late Pleistocene Snapping Turtles (Chelydra serpentina) from Southern Nevada
Van Devender TR and Tessman NT. 1975. Late Pleistocene Snapping Turtles (Chelydra serpentina) from Southern Nevada. Copeia. 1975(2):249-253
Remains of snapping turtles (Chelydra serpentina) are in the late Pleistocene vertebrate fauna near Glendale, Clark County, Nevada. The fossils are younger than the radioicarbon date for charcoal (. 33,000 y.b.p.) found 40 cm below the fossil turtles. The nearest living populations of Chelydra are in streams along the eastern base of the continental divide, at least 650 km away. The disperaal (about 850 jm) into southern Nevada probably occurred in the late Pleistocene (early Wisconsin Glacial Epoch). Possible routes and timing of the dispersal are discussed.
