Diagnosis Test a low trochospiral in the early stage, later uncoiling and becoming flattened, broad and irregular, chambers low and broad, of constant height but rapidly increasing in breadth, chamber infilling occurs at all stages, forming a solid central core in the coiled initial portion as in Pfenderina, but uncoiled stage with open chamber lumen concentrated on one side and with the infilling on the opposite side, producing a solid, nearly flat ventral plate; wall of imperforate microgranular calcite; apertural pores at the outer margin of the uncoiled portion and outer margin of the ventral surface, early coiled portion with a single subcameral tunnel that branches and is multiple in the uncoiled stage, additional tunnels intercalated as the uncoiled part widens. M. Jurassic (Bathonian or Callovian); Saudia Arabia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
