To better understand how fishes have accommodated lower jaw fangs through geologic time, we synthesize the multitude of ways living and extinct osteichthyans have housed large mandibular dentition. While the precise structure of fang accommodation seen in \u2020<jats:italic>Brazilichthys<\/jats:italic> has not been reported in any other osteichthyans, alternate strategies of upper jaw fenestration to fit mandibular fangs are present in some extant ray\u2010finned fishes\u2014the needlejaws <jats:italic>Acestrorhynchus<\/jats:italic> and the gars of the genus <jats:italic>Lepisosteus<\/jats:italic>. Notably, out of our survey, only the two aforementioned neopterygians bear upper jaw fenestration for the accommodation of mandibular fangs. We implicate the kinetic jaws of neopterygians in this trend, whereby large mandibular fangs are more easily fit between the multitude of upper jaw and palatal bones. The restricted space available in early osteichthyan jaws may have led to a proliferation of novel ways to accommodate large dentition. We recommend a greater survey of Paleozoic actinopterygian jaw morphology, in light of these results and other recent reevaluations of jaw structure in early fossil ray\u2010fins.<\/jats:p>","DOI":"10.1111\/joa.13798","type":"journal-article","created":{"date-parts":[[2022,11,26]],"date-time":"2022-11-26T18:33:01Z","timestamp":1669487581000},"page":"525-534","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Fitting fangs in a finite face: A novel fang accommodation strategy in a 280\u2010million\u2010year\u2010old ray\u2010finned fish"],"prefix":"10.1111","volume":"242","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9862-904X","authenticated-orcid":false,"given":"Rodrigo T.","family":"Figueroa","sequence":"first","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Michigan  Ann Arbor Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7093-1335","authenticated-orcid":false,"given":"James V.","family":"Andrews","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences University of Michigan  Ann Arbor Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,11,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0263593300002340"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0263593300001309"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-824360-2.00023-1"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.58433"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12862\u2010018\u20101264\u20104"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.20919"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.zool.2005.09.004"},{"key":"e_1_2_8_9_1","first-page":"37","article-title":"Basal Actinopterygian fish from the middle Devonian Bunga beds of New South Wales, Australia","volume":"130","author":"Choo B.","year":"2009","journal-title":"Proceedings of the Linnean Society of New South Wales"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0940\u20109602(98)80076\u20109"},{"key":"e_1_2_8_11_1","first-page":"13","article-title":"Fishes and Amphibians from the late Permian Pedra do Fogo formation of Northern of Brazil","volume":"34","author":"Cox C.B.","year":"1991","journal-title":"Palaeontology (oxford)"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12983\u2010018\u20100285\u20106"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev\u2010ecolsys\u2010122120\u2010122554"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724634.2020.1774771"},{"key":"e_1_2_8_15_1","first-page":"151","article-title":"Tegeolepis clarki (Newberry), a palaeonisciform from the upper Devonian Ohio shale","volume":"143","author":"Dunkle D.H.","year":"1973","journal-title":"Palaeontographica Abteilung A"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724634.2019.1639722"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsbl.2020.0766"},{"key":"e_1_2_8_18_1","unstructured":"FrickeR EschmeyerWN FongJD(2022)Eschmeyer's catalog of fishes \u2010 genera\/species by family\/subfamily.
