The Textulariida are a group of common foraminiferans that produce agglutinated shells, composed of foreign particles in an organic or calcareous cement. Previously they were taken to include all such species, but genetic studies have shown that they are not all closely related, and several superfamilies have been moved to the order Allogromiida. The remaining forms are sometimes divided into three orders: the Trochamminida and Lituolida (organic cement) and the Textulariida "sensu stricto" (calcareous cement). All three are known as fossils from the Cambrian onwards.
