Size: Diameter of holotype 0.25 mm. Extra details from original publication
Globigerina crassaformis Galloway & Wissler, WHITE, 1928, Jour. Paleontology, vol. 2, p. 193, pl. 27, fig. 1
This species is somewhat similar dorso-ventrally to G. crassula Cushman and Stewart but differs in its less angular periphery. A very similar four-chambered form with a small shallow umbilicus, and appressed chambers occurs rarely in the stratigraphically younger Chacra formation on the La Brea-Pariñas property. Editors' Notes Weiss published two papers in 1955 on the same material, in Micropaleontology and Journal of Paleontology. The details on the planktonic foraminifera are given in the paper in Micropaeontology but the original descriptions are in the paper in Journal of Paleontology.
