rotaliida rotaliida the rotaliida are an order of foraminifera, characterized by multilocular tests (shells) composed of bilamellar perforate hyaline lamellar calcite that may be optically radial or granular. rotaliidatemporal range: middle triassic - present, ammonia beccarii (rotaliidae) scientific classification domain: eukaryota clade: diaphoretickes clade: sar phylum: retaria subphylum: ectoreta infraphylum: foraminifera class: globothalamea order: rotaliidadelage & hérouard, 1896 suborders and superfamilies see text in form, rotaliid tests are typically enrolled, but may be reduced to biserial or uniserial, or may be encrusting with proliferated chambers. chambers may be simple or subdivided by secondary partitions; the surface is smooth, papillate, costate, striate, or cancellate; the aperture is simple or with an internal toothplate, entosolenian tube, or hemicylindrical structure; it may have an internal canal or stolen systems. rotaliids are primarily oceanic benthos, although some are common in shallower estuarine waters. they also include many important fossils, such as the nummulitids. taxonomy the rotaliida are now divided into the following superfamilies: order rotaliida delage & hérouard, 1896 suborder globigerinina delage & hérouard, 1896 superfamily globigerinitoidea bermúdez, 1961 superfamily globigerinoidea carpenter et al., 1862 superfamily globorotalioidea cushman, 1927 superfamily globotruncanoidea brotzen, 1942 † superfamily guembelitrioidea montanaro gallitelli, 1957 superfamily hantkeninoidea cushman, 1927 superfamily heterohelicoidea cushman, 1927 superfamily planomalinoidea bolli et al., 1957 † superfamily rotaliporoidea sigal, 1958 † superfamily acervulinoidea schultze, 1854 superfamily annulopatellinoidea loeblich & tappan, 1964 superfamily asterigerinoidea d'orbigny, 1839 superfamily bolivinitoidea cushman, 1927 superfamily bolivinoidea glaessner, 1937 superfamily buliminoidea jones, 1875 superfamily cassidulinoidea d'orbigny, 1839 superfamily chilostomelloidea brady, 1881 superfamily delosinoidea parr, 1950 superfamily discorbinelloidea sigal, 1952 superfamily discorboidea ehrenberg, 1838 superfamily eouvigerinoidea cushman, 1927 † superfamily fursenkoinoidea loeblich & tappan, 1961 superfamily glabratelloidea loeblich & tappan, 1964 superfamily loxostomatoidea loeblich & tappan, 1962 superfamily nonionoidea schultze, 1854 superfamily nummulitoidea blainville, 1827 superfamily orbitoidoidea schwager, 1876 † superfamily planorbulinoidea schwager, 1877 superfamily pleurostomelloidea reuss, 1860 † superfamily rotalioidea ehrenberg, 1839 superfamily serioidea holzmann & pawlowski, 2017 superfamily siphoninoidea superfamily turrilinoidea cushman, 1927 family murrayinellidae holzmann & pawlowski, 2017 baculogypsina sphaerulata (calcarinidae) miniacina miniacea (homotrematidae) heterostegina depressa (nummulitidae) planulina limbata (planulinidae) ammonia tepida (rotaliidae) ammonia beccarii (rotaliidae), elphidium excavatum (elphidiidae), buccella frigida (discorbidae) and verneuilinulla advena
