Late Pleistocene Salamander (Caudata; Plethodontidae) from Santa Rosa Island, Northern Channel Islands, California
We present the first record of a late Pleistocene salamander, Batra- choseps (Plethodontidae; Bolitoglossini) from the Northern Channel Islands. Fos- sils were recovered in sediments by using 700 |Jim mesh wet sieving. Ocean currents could have transported any or all of the known seven families of sala- manders presently inhabiting coastal USA to the islands. We suggest that only the Plethodontini and Bolitoglossini were likely to successfully colonize the Pleis- tocene-age coalesced island, Santarosae, due to their lack of an aquatic larval stage. The recovery of Batrachoseps from Carrington Point implies a moist, or- ganic understory, but it does not dictate a particular habitat reconstruction.
