Current identification:
[Translation from French using google translate] Perforated limestone test, consisting of 2 winding coils of 5 to 6 compartments each. The chambers of the first coil are globose and small, while the boxes of the second turn are arched. Spiral face: Contour lobed, sutures in relief, the two hulls are visible. Umbilical: Main umbilical opening. Subradial sutures - radial, depressed. The lobed chambers, in the central part of each chamber, is a crest. Tegilla developed with intralaminic accessory openings. A concave - convex profile with two distinct sections separated by a broad peripheral band; the section of the spiral side is in the spiral plane. The last chamber is about 2-3 times higher than the first ones. It forms with the dorsal side an angle of 90-95 ° [Translation from French using google translate] Remarks: From the phylogenetic point of view the ancestral form of Abathomphalus asteroidalis n. sp. is Globotruncana gagnebini Tilev. Stratigraphic distribution: Abathomphalus asteroidalis n. sp. is in the upper Maastrichtian.
