Abstract
Detailed description of the cranial anatomy of the rhynchosaur previously known as Scaphonyx sulcognathus allows its assignment to a new genus Teyumbaita. Two nearly complete skulls and a partial skull have been referred to the taxon, all of which come from the lower part of the Caturrita Formation, Upper Triassic of Rio Grande do Sul, southern Brazil. Cranial autapomorphies of Teyumbaita sulcognathus include anterior margin of nasal concave at midline, prefrontal separated from the ascending process of the maxilla, palatal ramus of pterygoid expanded laterally within palatines, dorsal surface of exoccipital markedly depressed, a single tooth lingually displaced from the main medial tooth-bearing area of the maxilla, and a number of other characters (such as skull broader than long; a protruding orbital anterior margin; anguli oris extending to anterior ramus of the jugal; bar between the orbit and the lower temporal fenestra wider than 0·4 of the total orbital opening; mandibular depth reaching more than 25 of the total length) support its inclusion in Hyperodapedontinae. T. sulcognathus is the only potential Norian rhynchosaur, suggesting that the group survived the end-Carnian extinction event.

Two nearly complete skulls and a partial skull have been referred to the taxon, all of which come from the lower part of the Caturrita Formation, Upper Triassic of Rio Grande do Sul, southern Brazil. Cranial autapomorphies of Teyumbaita sulcognathus include anterior margin of nasal concave at midline, prefrontal separated from the ascending process of the maxilla, palatal ramus of pterygoid expanded laterally within palatines, dorsal surface of exoccipital markedly depressed, a single tooth lingually displaced from the main medial tooth-bearing area of the maxilla, and a number of other characters (such as skull broader than long; a protruding orbital anterior margin; anguli oris extending to anterior ramus of the jugal; bar between the orbit and the lower temporal fenestra wider than 0·4 of the total orbital opening; mandibular depth reaching more than 25 of the total length) support its inclusion in Hyperodapedontinae. T. sulcognathus is the only potential Norian rhynchosaur, suggesting that the group survived the end-Carnian extinction event.</abstract><subject><genre></genre><topic>Caturrita Formation</topic><topic>Norian</topic><topic>Rhynchosauria</topic><topic>skull anatomy</topic><topic>Teyumbaita sulcognathus</topic></subject><relatedItem type="host"><titleInfo><title>Earth and Environmental Science Transactions of the Royal Society of Edinburgh</title></titleInfo><titleInfo type="abbreviated"><title>Earth and Environmental Science Transactions of the Royal Society of Edinburgh</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><identifier type="ISSN">1755-6910</identifier><identifier type="eISSN">1755-6929</identifier><identifier type="PublisherID">TRE</identifier><part><date>2010</date><detail type="volume"><caption>vol.</caption><number>101</number></detail><detail type="issue"><caption>no.</caption><number>1</number></detail><extent unit="pages"><start>27</start><end>52</end><total>26</total></extent></part></relatedItem><identifier type="istex">D738A0E6FE8D03B4D2E68CBC8CF378A8B3C34BB5</identifier><identifier type="ark">ark:/67375/6GQ-5PKG4C1S-K</identifier><identifier type="DOI">10.1017/S1755691010009060</identifier><identifier type="PII">S1755691010009060</identifier><identifier type="ArticleID">00906</identifier><accessCondition type="use and reproduction" contentType="copyright">Copyright © Royal Society of Edinburgh 2010</accessCondition><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-G3RCRD03-V">cambridge</recordContentSource><recordOrigin>Copyright © Royal Society of Edinburgh 2010</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/D738A0E6FE8D03B4D2E68CBC8CF378A8B3C34BB5/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
