An Oligocene (Orellan) Sirenian Fron the Bucatunna Formation of Alabama

Abstract

Tertiary sirenians from the New World have been recently reviewed by Reinhart (1976) and Savage (1976). The earliest New World sirenians are known from the presence of pachyostose ribs in Eocene strata of the southeastern United States and from an Eocene skull and mandible from Jamaica.
