miliolida miliolida the miliolida are an order of foraminifera with calcareous, porcelacous tests that are imperforate and commonly have a pseudochitinous lining. tests are composed of randomly oriented calcite needles that have a high proportion of magnesium along with organic material. tests lack pores and generally have multiple chambers. miliolidatemporal range: carboniferous - recent quinqueloculina sp. from donegal bay, ireland. scientific classification domain: eukaryota (unranked): sar (unranked): rhizaria phylum: retaria subphylum: foraminifera class: tubothalamea order: miliolida superfamilies alveolinoidea ehrenberg, 1839 cornuspiroidea schultze, 1854 nom. transl. bogdanovich in subbotina et al., 1981 milioloidea ehrenberg, 1839 nubecularioidea soritoidea ehrenberg, 1839 squamulinoidea reuss & fritsch, 1861 miliolids, which range from the carboniferous to recent, are benthic foraminifera abundant in shallow waters such as in estuaries and along coastlines, though they also include deepwater oceanic forms. 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.
