The amphibians and reptiles from the Early Pleistocene of Coste San Giacomo (Anagni Basin, Italy)

The site of Coste San Giacomo, in the Anagni Basin, is renowned for its mammal fauna of Early Pleistocene (Gelasian) age, including 32 taxa of small and large mammals. Adding to these, a small amount of remains of amphibians and reptiles was also recovered during recent excavations focused on collecting small vertebrates as well. The analysis of these remains resulted in the identification of a total of at least six different taxa: three anurans (Bufonidae indet., Pelophylax sp., and Rana sp.) and three reptiles (Lacertidae indet., Pseudopus sp., and Natrix sp.). This assemblage is comprised of taxa that are common in the Italian Quaternary, but also presents the first occurrence of the large anguid Pseudopus from the Apennine Peninsula in this period. On the whole, the herpetofauna indicates the presence of humid conditions in CSG at the moment of deposition of the bone bed that yielded the vertebrate remains.
