Abstract

A diverse late Eocene, lower vertebrate fauna is described based on collections made at the Crow Creek Quarry, in St. Francis County, Arkansas. Many of the taxa are reported from the late Eocene deposits of Arkansas for the first time. Paleoecological conditions evidenced by the vertebrate remains indicate deposition occurred under hyposaline conditions adjacent to warm marine waters. This is in agreement with earlier studies of associated molluscan remains and sporomorphs found within the region.
