A Mid-Pleistocene (Irvingtonian) Herpetofauna From a Cave in South Central Texas

At least 24 species of amphibians and reptiles are identified from the mid-Pleistocene Fyllan Cave Fauna. Travis County, Texas. This is the largest mid-Pleistocene herpetofauna known from the Texas, and one of the largest mid-Pleistocene herpetofaunas known from the United States. Only the large terrestrial tortoise represent an extinct species, but three extralimital forms indicate that winters in the area were milder than they are today. The fossils appear to have been subjected to considerable post-mortem- transport
