百分之九十一的钙质有孔虫属在二叠纪末大规模灭绝期间灭绝。早三叠世是一个生存阶段，其特征是灾害形式短暂扩散，然后是长期的低多样性时期。米利奥利达目和拉格尼达目分别在安尼阶早期和晚期经历了有限的分类学重新多样化。所有的fusulinoidean fusulinides在二叠纪晚期都灭绝了，只有两个非fusulinoidean属持续到了早三叠世。在三叠纪晚期该目完全灭绝之前，三叠纪的fusulinides多样化至仅五个属。 Involutinides 起源于奥莱尼克时代，其祖先未知。直到三叠纪晚期，它们才显着多样化。引用本文：J.R.

Ninety-one percent of calcareous foraminiferal genera became extinct during the end-Permian mass extinction. The Early Triassic Epoch was a survival phase characterized by a short-lived proliferation of disaster forms and then a prolonged interval of low diversity. The orders Miliolida and Lagenida experienced limited taxonomic re-diversification in Early and Late Anisian time, respectively. All fusulinoidean fusulinides became extinct in Late Permian time, and only two non-fusulinoidean genera persisted into the Early Triassic. Triassic fusulinides diversified to just five genera before the order became entirely extinct in Late Triassic time. Involutinides originated in Olenekian time from an unknown ancestor. They did not significantly diversify until Late Triassic time. To cite this article: J.R. Groves, D. Altiner, C. R. Palevol 4 (2005).
