The Olivoidea, olives, are a group of burrowing, predatory gastropods found in warm waters. They commonly possess a glossy, bullet-shaped shell and a large, muscular head and foot with lateral parapodia embracing the shell. The basal Pseudolividae, however, have ovoid to fusiform shells covered by periostracum and lack foot parapodia. The genus Benthobia is similar to Pseudolividae (differing in having a multispiral protoconch) but is placed by molecular analysis closer to other Olivoidea. True olives of the subfamily Olivinae have highly glossy, solid shells with a cylindrical shape, low spire, and a long narrow aperture with several columellar plaits, and without an operculum. Members of the Ancillariidae have a thinner, less glossy shell, usually with a wider aperture and higher spire, and sometimes with a small operculum (Wilson & Gillett 1971). Vanpalmeria is a Palaeocene genus with a biconic shell covered by several layers of feltlike calcite.
