globothalamea globothalamea globothalamea comprises a class of multichambered foraminifera based in part on ssu rdna evidence; the other is tubothalamea. globothalameatemporal range: devonian? - recent ammonia beccarii scientific classification domain: eukaryota clade: diaphoretickes clade: sar phylum: retaria subphylum: ectoreta infraphylum: foraminifera class: globothalameapawlowski, holzmann, & tyszka, 2013 orders textularia (superorder) lituolida loftusiida textulariida carterinida robertinida rotaliida †fusulinida six orders are included, which vary notably in composition, wall structure, and chamber arrangement. the lituolida, loftusiida, and textulariida (as emended) have tests (shells) of agglutinated matter, glued together by various cements, but differ in chamber arrangement, wall structure, and complexity. in contrast the carterinida, robertinida and rotaliida, with buliminids lumped into the rotaliida, have calcareous tests. those of rotaliid genera, which vary considerably, are of perforate hyaline (glassy) calcite. in contrast the carterinida have tests composed of bundled calcite spicules. the robertida differ in being composed, instead, of aragonite. subclass textulariia orders: lituolida – loftusiida – textulariida unassigned orders: carterinida – robertinida – rotaliida
