The Globothalamea is a major group of multi-chambered Foraminifera in which the chambers are primarily globular or crescent-shaped. Basal lineages, corresponding to the order ‘Textulariida’, have an agglutinated test; other subgroups have a test composed of calcite or aragonite (Pawlowski et al. 2013).

Characters (from Pawlowski et al. 2013): Test multi-chambered, typically trochospirally enrolled but may be triserial, biserial or uniserial; chambers globular or crescent-shaped in early stage; wall agglutinated or calcareous. SSU rRNA gene length averaging 3500 nt (3000–4000 nt), GC content of about 40%; conserved motive present in variable region 41f of SSU rDNA.
