{"pk":41712,"title":"Two new Miocene limpets (Fissurellidae) from southern California, with notes on other fossil occurrences of the family in northwestern North America","subtitle":null,"abstract":"Two new fissurellid limpets (Mollusca: Gastropoda: Fissurellidae), \nFissurella\n? \nstantoni\n n. sp. and\n Scelidotoma aldersoni\n n. sp., are described from Miocene deposits in southern California. \nFissurella\n? \nstantoni\n is described from a single specimen from the middle Miocene Topanga Canyon Formation in the Santa Monica Mountains, Los Angeles County, California. \nScelidotoma aldersoni\n is described from two specimens, one from the middle Miocene Topanga Canyon Formation, and another provisionally (cf.) identified specimen of an internal mold from the middle Miocene “Vaqueros” Formation on Santa Cruz Island, Santa Barbara County, southern California. Other unreported fossil occurrences of \nScelidotoma\n are a juvenile specimen attributed only to genus collected in the middle Eocene Crescent Formation in Washington state and \nS. bella\n from the Pliocene part of the San Diego Formation, San Diego County, California. The \nScelidotoma\n occurrences extend the chronostratigraphic range of \nS. bella\n from the Holocene (living) to the middle Pliocene, and the range of the genus back to the middle Eocene.","language":"en","license":{"name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0","short_name":"CC BY-NC-SA 4.0","text":"<p><!-- x-tinymce/html --></p>\n<p>Readers are free to:</p>\n<ul>\n<li><strong>Share</strong> — copy and redistribute the material in any medium or format</li>\n<li><strong>Adapt</strong> — remix, transform, and build upon the material<br><br>The licensor cannot revoke these freedoms as long as you follow the license terms.</li>\n</ul>\n<p>Under the following terms:</p>\n<ul>\n<li><strong>Attribution</strong> — You must give appropriate credit , provide a link to the license, and indicate if changes were made .
