Here we present the oldest actinopterygian tongue bite, derived from the gill skeleton, in the Middle Pennsylvanian (approx. 310 Ma) \u2020\n                    <jats:italic toggle=\"yes\">Platysomus parvulus<\/jats:italic>\n                    . Unrelated to extant tongue biters, this deep-bodied taxon possesses a large, multipartite basibranchial tooth plate opposing an upper tooth field centred on the vomer. This branchial structure occurs in conjunction with toothed jaws, indicating a role for both the basibranchial plate and jaws in feeding. \u2020\n                    <jats:italic toggle=\"yes\">P. parvulus<\/jats:italic>\n                    illustrates the assembly of the tongue bite in the geologically younger \u2020Bobasatraniidae: large opposing dorsal (vomerine) and ventral (basibranchial) crushing plates associated with toothless jaws. The origin of tongue bites falls within the Carboniferous actinopterygian radiation, although it postdates the first signs of the consumption of hard prey (durophagy) in other ray-finned lineages by several million years. This lends support to a protracted model of actinopterygian diversification in the aftermath of the end-Devonian extinction.\n                  <\/jats:p>","DOI":"10.1098\/rsbl.2025.0270","type":"journal-article","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T07:12:11Z","timestamp":1756883531000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Tongue-bite apparatus highlights functional innovation in a 310-million-year-old ray-finned fish"],"prefix":"10.1098","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9267-4392","authenticated-orcid":true,"given":"Sam","family":"Giles","sequence":"first","affiliation":[{"name":"School of Geography, Earth and Environmental Sciences, University of Birmingham","place":["Birmingham, UK"]},{"name":"Natural History Museum","place":["London, UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9748-2066","authenticated-orcid":true,"given":"Matthew","family":"Kolmann","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Louisville","place":["Louisville, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0114-7384","authenticated-orcid":true,"given":"Matt","family":"Friedman","sequence":"additional","affiliation":[{"name":"Natural History Museum","place":["London, UK"]},{"name":"Museum of Paleontology, University of Michigan","place":["Ann Arbor, USA"]},{"name":"Department of Earth and Environmental Sciences, University of Michigan","place":["Ann Arbor, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1546-5098(05)23003-0"},{"key":"e_1_3_8_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature06062"},{"key":"e_1_3_8_4_2","doi-asserted-by":"publisher","DOI":"10.1643\/0045-8511(2001)001[0372:TBAOOF]2.0.CO;2"},{"key":"e_1_3_8_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7580.2009.01056.x"},{"key":"e_1_3_8_6_2","doi-asserted-by":"publisher","DOI":"10.2307\/2412950"},{"key":"e_1_3_8_7_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-ecolsys-111720-010447"},{"key":"e_1_3_8_8_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0094837300005352"},{"key":"e_1_3_8_9_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2011.2454"},{"key":"e_1_3_8_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/zoj.12054"},{"key":"e_1_3_8_11_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1755691018000816"},{"key":"e_1_3_8_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-87027-y"},{"key":"e_1_3_8_13_2","article-title":"A new predatory actinopterygian from the Tournaisian of Nova Scotia provides insight into the evolution of actinopterygian feeding","author":"Wilson CD","year":"2025","unstructured":"Wilson CD, Mansky CF, Anderson JS. 2025 A new predatory actinopterygian from the Tournaisian of Nova Scotia provides insight into the evolution of actinopterygian feeding.
