Citation: Globigerina danvillensis Howe & Wallace 1932Rank: SpeciesType specimens: HVH 712Type sample (& lithostrat): Jackson, Upper Horizon (Bed 2), light yellow clay. Common in both horizons.Type age (chronostrat): Upper Eocene.Type locality: Danville Landing on the Ouachita River, Catahoula Parish, Louisiana, U. S.

Original Description Test small, trochoid but nearly planispiral, periphery lobate; chambers few, about eight visible on the dorsal side, about four in the last-formed whorl, almost spherical in shape; sutures depressed; wall calcareous, finely spinose, perforate; aperture an almost circular opening on the ventral side not quite centered on the periphery. Size: Diameter 0.2 mm.; diameter of largest chamber 0.13 mm Etymology: Extra details from original publication This species differs from Globigerina pseudo-bulloides Plummer in the shape of the aperture and the arrangement of the early coil. Editors' Notes The original combination is given as Globorotalia danvillensis in some sources (e.g Eocene & Oligocene atlases) but is Globigerina danvillensis according to other sources, including the Ellis & Messina catalog.
