| Abstract | Two new genera and three new species of extinct buccinoid gastropods are described and named from the Pacific slope of North America. The buccinid? Ornopsis? dysis new species is from uppermost Maastrichtian (uppermost Cretaceous) strata in the Dip Creek area, San Luis Obispo County, west-central California. The fasciolarine fasciolarid? Saxituberosa new genus is comprised of the lineage Saxituberosa fons new species, from lower Paleocene (Danian) strata in Los Angeles County, southern California, and Saxituberosa titan (Waring, 1917), from middle Paleocene (Selandian) strata in Ventura and Los Angeles counties, southern California, and northern Baja California, Mexico. The fusinine fasciolarid? Perrilliata califia new genus and new species is known from middle Paleocene (Selandian) strata in Ventura County, southern California and northern Baja California, Mexico. Ornopsis? dysis and Perrilliata califia are similar in morphology and geologic age to Gulf Coast Ornopsis (Ornopsis) glenni Wade, 1916, and Fasciolaria? plummeri Gardner, 1933, respectively; whereas probable congeners for Saxituberosa are unknown, and it appears to be endemic to the northeastern Pacific. |
