- W2027720687 abstract "Gastroliths are stones present in the stomach of many vertebrate species and their occurrence in fossil and living vertebrates is well documented in the scientific literature. Vertebrate groups, especially aquatic tetrapods, including Crocodilia, Spheniscidae, Mysticeti, Odontoceti and Pinnipedia, and the extinct Plesiosauria are examples of such occurrence (for a complete review see Taylor, 1993). Although there is a paucity of detailed information about gastroliths in individual species of pinnipeds, there are records of their occurrence in species in all three families (Phocidae, Odobenidae and Otariidae, Taylor, 1993). In otariids, gastroliths have been described in Zalophus californianus (Scheffer and Neff, 1948) , Neophoca c inerea , Phocarctos hookeri and Arctocephalus pusillus (Marlow, 1975), Eumetopias jubatus (Fiscus and Baines, 1966) and Callorhinus ursinus (Taylor, 1993). In the case of the South American sea lion, Otaria byronia (Pinnipedia, Otariidae) occurrence of gastroliths was first reported in 1934 (Hamilton, 1934), and more recently by Vaz-Ferreira (1981). Here we report the presence of gastroli ths in seven specimens of South American sea lions collected on the southern coast of Brazil. We also present measurements and weight of the gastroliths (individual and total) from each specimen (see Table 1) . The occurrence of gastroliths in the stomach contents of Pinnipedia has been identified as an important aspect of their biology (Riedman, 1990). However, no mention is made of gastroliths in recent textbooks on marine mammals (e.g. Berta and Sumich, 1999; Perrin et al., 2001) the word ‘gastrolith’ appearing in neither the glossary nor the remissive index. In total 47 specimens of Otaria byronia were collected during beach surveys along the coast of Rio Grande do Sul State (between 30° and 31° South), between 1990 and 1998. Skulls and gastroliths from specimens are deposited in Mammal Collection at Museu de Ciencias Naturais (MCN), Fundacao Zoobotânica do Rio Grande do Sul, Porto Alegre, Brazil.
