Reptiles from the late Eocene Jackson Group of Arkansas
Abstract
New reptilian fossils from the latest middle Eocene to late Eocene Crow Creek local faunafrom the Jackson Group of St. Francis County, Arkansas, add four turtles and two crocodilians to the fauna. These include a new species of the carettochelyid Anosteira, the kinosternid Xenochelys, the dermatemydid Baptemys, an unidentified cheloniid, and crocodilians cf. Borealosuchus and an alligatorid. The giant snake, Pterosphenus schucherti, was also a member of the reptilian fauna. Several of these are the most easterly records for these taxa.
