Editing Jurassic (section)

===== Bivalves =====
The end-Triassic extinction had a severe impact on bivalve diversity, though it had little impact on bivalve ecological diversity. The extinction was selective, having less of an impact on deep burrowers, but there is no evidence of a differential impact between surface-living (epifaunal) and burrowing (infaunal) bivalves.<ref>{{Cite journal|last1=Ros|first1=Sonia|last2=De Renzi|first2=Miquel|last3=Damborenea|first3=Susana E.|last4=Márquez-Aliaga|first4=Ana|date=November 2011|title=Coping between crises: Early Triassic–early Jurassic bivalve diversity dynamics|url=https://linkinghub.elsevier.com/retrieve/pii/S0031018211004573|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|language=en|volume=311|issue=3–4|pages=184–199|doi=10.1016/j.palaeo.2011.08.020|bibcode=2011PPP...311..184R|hdl=11336/81358 |hdl-access=free}}</ref> Bivalve family level diversity after the Early Jurassic was static, though genus diversity experienced a gradual increase throughout the period.<ref>{{Cite journal|last1=Mondal|first1=Subhronil|last2=Harries|first2=Peter J.|date=February 2016|title=The Effect of Taxonomic Corrections on Phanerozoic Generic Richness Trends in Marine Bivalves with a Discussion on the Clade's Overall History|url=https://www.cambridge.org/core/product/identifier/S0094837315000354/type/journal_article|journal=Paleobiology|language=en|volume=42|issue=1|pages=157–171|doi=10.1017/pab.2015.35|bibcode=2016Pbio...42..157M |s2cid=87260961|issn=0094-8373}}</ref> [[Rudists]], the dominant reef-building organisms of the Cretaceous, first appeared in the Late Jurassic (mid-Oxfordian) in the northern margin of the western Tethys, expanding to the eastern Tethys by the end of the Jurassic.<ref>{{Cite journal|last1=Sha|first1=J.|last2=Cestari|first2=R.|last3=Fabbi|first3=S.|date=April 2020|title=Paleobiogeographic distribution of rudist bivalves (Hippuritida) in the Oxfordian–early Aptian (Late Jurassic–Early Cretaceous)|url=https://linkinghub.elsevier.com/retrieve/pii/S0195667119302782|journal=Cretaceous Research|language=en|volume=108|pages=104289|doi=10.1016/j.cretres.2019.104289|bibcode=2020CrRes.10804289S |s2cid=210248232}}</ref>
