Diagnosis Test a low cone to nearly discoidal, up to 12 mm in diameter, apex rounded to mammilate, large embryonic apparatus, with equally well-developed supra-and subembryonal zones, in contrast to the weakly developed subembryonal zone of Orbitolina, both sub-and supraembryonal chambers with marginal zone subdivided by numerous exoskeletal beams that are perpendicular to the outer walls, early postembryonic chambers rectilinear, low, and discoidal, marginal zone subdivided by radial beams of two or three orders and by horizontal rafters, resulting in the formation of numerous rectangular chamberlets, welldeveloped radial zone of continuing first order beams that thicken rapidly at the junction of the marginal and radial zones, becoming triangular in section and zigzag in plan, central zone with thinner and flatter beams that are discontinuous because of the large number of pores in the central area, central zone may be lacking in later chambers that are annular rather than discoidal; wall of fine silt-to claysized agglutinated particles, with some large calcite grains; small apertural pores lie in reentrants in the main beams in the radial zone, become more numerous inward to the junction with the central zone, and are abundant in the central zone. L. Cretaceous (Albian) to U. Cretaceous (L. Cenomanian); USA: Texas; Spain; Italy; Yugoslavia; China: Tibet; India. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
