This checklist is a sequel to the one published by A. Myra Keen and Herdis Bentson in 1944 and is an alphabet- ical listing of California marine Paleogene–Neogene mollusk in the published literature spanning the interval of 1944 through 2020. The original data are given for each species and subspecies of bivalves, gastropods, (polyplacophorans),or subspecies scaphopods, described and and/or cephalopods. figured Where detected, formation names, ages, , systematics, and specimen disposition were corrected. A total of 559 genera and 1,698 species/subspecies were tabulated, with the bivalves and gastropods being the most abundant taxa. Bivalve and gastropod diversity steadily built up during the Paleocene, nearly doubled during the warm time, declined greatly during the cool time of the Oligocene, rebounded to its high- est peak in the and then declined slightly during the . The other classes represented only minor faunal components. Chitons were only reported from the Pliocene, and cephalopods had their highest diversity during the Paleocene and Eocene. Bivalve genera having the highest diversity are: Glycymeris, Ma- coma, Mactromeris, Nuculana, and Tellina. Gastropod genera having the highest diversity are Cancellaria and Turritella. It is very likely that the Turritella overnamed. The high point of research productivity of published reports on California Paleogene-Neogene mollusks was in 1990–1994, and a species/subspecies complex has been significantly Menlo Park USGS Paleontology and Stratigraphy facility. An overall decline in productivity has continued, with noticeable upticks in 2003 and insignificant recent years. decline occurred in 1995–1996, following the closure of the

McFarland. In retirement, Bentson was active in conservation organi- zations in California, maintained contact with numerous relatives in Denmark as well as in the United States, and compiled a history focusing on her family’s migration to and their experiences in the Western Hemisphere. She passed away at the age of 92 on September 8, 2006.
