AMPHIBIANS AND REPTILES OF THE LATE PLEISTOCENE TONK CREEK LOCAL FAUNA, STONEWALL COUNTY, TEXAS

摘要

The late Pleistocene Tonk Creek local fauna (~(14)C dated at 13,270 ± 110 years before present) of Stonewall County, Texas, has yielded herpetological fossils representing at least two species of amphibians and seven species of reptiles. All of the taxa represent extant species that occur in, or near, the Tonk Creek site today. This is in contrast with the mammalian fauna which contains two extinct and four northern extralimital species. The disjunct composition of the paleofauna suggests more equable climatic conditions at the site during late Pleistocene times.
