TheMiliolida are an order offoraminifera withcalcareous, porcelacous tests that are imperforate and commonly have a pseudochitinous lining.[2] Tests are composed of randomly orientedcalcite needles that have a high proportion ofmagnesium along with organic material. Tests lack pores and generally have multiple chambers.
Miliolids, which range from theCarboniferous to recent, arebenthic Foraminifera abundant in shallow waters such as inestuaries and along coastlines, though they also include deepwater oceanic forms.[3]
The order Miliolida, sometimes referred to as a suborder, the Miliolina, is divided on the basis of differences in test morphology into five recognized superfamilies.
