Abstract

Elasmostoma bajaensis n. sp., a pharetronid calcareous sponge, is described from the lower Eocene (P8 or P9 Zone) portion of the Bateque Formation, Baja California Sur, Mexico. This is the first Tertiary record of this genus and its first Western Hemisphere occurrence. Elasmostoma has been previously reported only from Jurassic and Cretaceous strata of Western Europe.
