RMDTGDMT–Foraminiferal limestone

Amphistegina quoyi, Print, Amphistegina is a genus of foraminiferal protists included in the Rotaliida with a stritigraphic range extending from the Eocene to recent and a cosmopolitan distribution. The test is an asymmetrically biconvex trochospiral that may be bi-involute or partially evolute on the spiral side. Chambers are numerous, broad. and low, strongly curved back at the periphery to form chamber prolongations. The umbilical side is stellate, like that of Asterigerina, and has a distinct umbilical plug. The wall is calcareous, optically radial; the surfacce finely perforate and smooth Stock Photo
