These richly fossiliferous Eocene deposits belong to the most thoroughly documented marine fossil faunas. The fauna of the Claiborne Group (Alabama, Texas) has been documented early by Conrad (1833) and Lea (1833), largely describing the same species with Conrad's earlier publication having priority. Subsequent smaller publications (Conrad (1834, 1860); Heilprin (1881); Aldrich (1886, 1921, 1931); De Gregorio (1890); Cossmann (1893)) added to the knowledge of the molluscan fauna. The malacofauna of the Stone City Formation of Texas was documented by Emerson & Emerson (2001).
Palmer's (1937) monumental work summerasised the available knowledge and should be considered the starting point of any study on the subject.
