Title: | Bottom-Feeding Plesiosaurs | Contributor(s): | McHenry, Colin R (author); Cook, Alex G (author); Wroe, Stephen (author) | Publication Date: | 2005-10-07 | DOI: | 10.1126/science.1117241 | Handle Link: | https://hdl.handle.net/1959.11/30766 | Abstract: | Elasmosaurid plesiosaurs were an important part of Cretaceous marine reptile communities and are generally considered to have been predators of small, agile, free-swimming fish and cephalopods. Two elasmosaurid specimens from Aptian and Albian deposits in Queensland, Australia, include fossilized gut contents dominated by benthic invertebrates: bivalves, gastropods, and crustaceans. Both specimens also contained large numbers of gastroliths (stomach stones). These finds point to a wider niche than has previously been supposed for these seemingly specialized predators and may also influence long-running controversy over the question of gastrolith function in plesiosaurs. | Publication Type: | Journal Article | Source of Publication: | Science, 310(5745), p. 75-75 | Publisher: | American Association for the Advancement of Science (AAAS) | Place of Publication: | United States of America | ISSN: | 1095-9203 0036-8075 |
