==== Brachiopods ====
[[Brachiopod]] diversity declined during the Triassic–Jurassic extinction. Spire-bearing brachiopods ([[Spiriferinida]] and [[Athyridida]]) did not recover their biodiversity, becoming extinct in the TOAE.<ref name="Vörös-2016">{{Cite journal|last1=Vörös|first1=Attila|last2=Kocsis|first2=Ádám T.|last3=Pálfy|first3=József|date=September 2016|title=Demise of the last two spire-bearing brachiopod orders (Spiriferinida and Athyridida) at the Toarcian (Early Jurassic) extinction event|url=https://linkinghub.elsevier.com/retrieve/pii/S0031018216302140|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|language=en|volume=457|pages=233–241|bibcode=2016PPP...457..233V|doi=10.1016/j.palaeo.2016.06.022}}</ref> [[Rhynchonellida]] and [[Terebratulida]] also declined during the Triassic–Jurassic extinction but rebounded during the Early Jurassic; neither clade underwent much morphological variation.<ref>{{Cite journal|last1=Vörös|first1=Attila|last2=Kocsis|first2=Ádám T.|last3=Pálfy|first3=József|date=2019|title=Mass extinctions and clade extinctions in the history of brachiopods: Brief review and a post-Paleozoic case study|url=https://riviste.unimi.it/index.php/RIPS/article/view/12184|journal=Rivista Italiana di Paleontologia e Stratigrafia|language=en|volume=125|issue=3|doi=10.13130/2039-4942/12184|issn=2039-4942|access-date=2020-12-25|archive-date=2020-09-01|archive-url=https://web.archive.org/web/20200901035135/https://riviste.unimi.it/index.php/RIPS/article/view/12184|url-status=dead}}</ref> Brachiopods substantially declined in the Late Jurassic; the causes are poorly understood.
