Abstract
Tasmanites, Tytthodiscus, and leiospheres assignable to Leiosphaeritiia, are present in Neogene shales of the Gulf Coast area of southern Louisiana, U.S.A. Seven species of Tasmanites, one species of Tytthodiscus, and two species of Leiosphaeridia are described from sidewall core samples; all except Tytthodiscus are new.
