Miocene Herpetofaunas from the Central Gulf Coast, USA: Their Paleoecology, Biogeography, and Biostratigraphy

The late Barstovian Fort Polk herpetofauna represents the most diverse herpetofauna on the Gulf Coast, USA, and includes 15 genera from ten families. The herpetofaunal composition of Fort Polk and Miocene east Texas localities is similar enough to Great Plains localities that they are all considered...
