Research on the ontogeny of non\u2010mammaliaform cynodonts has offered significant contributions to our understanding of these aspects. Here, we aim to describe and discuss the intraspecific and ontogenetic variation of the skull of the Brazilian traversodontid\n                    <jats:italic>Siriusgnathus niemeyerorum<\/jats:italic>\n                    (Candel\u00e1ria Sequence, Upper Triassic). We evaluated an ontogenetic series of the species through qualitative comparison and allometric analyses using cranial measures. Our findings reveal several trends during skull growth, including a relative increase in rostrum length, a relative decrease in orbit size, and changes in the zygomatic arch and temporal fenestra proportions. These patterns, when analyzed in the context of the adductor musculature, may be correlated with changes in feeding behaviour, similar to those described for the gomphodontosuchine\n                    <jats:italic>Exaeretodon argentinus<\/jats:italic>\n                    . We also report changes in cranial ornamentation, bone fusion, and suture complexity throughout ontogeny. Overall, this study provides a greater understanding of the cranial ontogenetic patterns of\n                    <jats:italic>S. niemeyerorum<\/jats:italic>\n                    , contributing to the knowledge of its intraspecific variation. The possible ecological implications of these findings highlight the importance of ontogenetic studies for elucidating the biology of extinct taxa.\n                  <\/jats:p>","DOI":"10.1002\/jmor.70047","type":"journal-article","created":{"date-parts":[[2025,4,18]],"date-time":"2025-04-18T07:16:16Z","timestamp":1744960576000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ontogeny of a Brazilian Late Triassic Traversodontid (Cynodontia, Cynognathia): Anatomical and Paleoecological Implications"],"prefix":"10.1002","volume":"286","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2722-4528","authenticated-orcid":false,"given":"L\u00edvia","family":"Roese\u2010Miron","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s\u2010Gradua\u00e7\u00e3o em Biodiversidade Animal Universidade Federal de Santa Maria Santa Maria Rio Grande do Sul Brazil"},{"name":"Centro de Apoio \u00e0 Pesquisa Paleontol\u00f3gica da Quarta Col\u00f4nia Universidade Federal de Santa Maria (CAPPA\/UFSM) S\u00e3o Jo\u00e3o do Pol\u00easine Rio Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8139-1493","authenticated-orcid":false,"given":"Leonardo","family":"Kerber","sequence":"additional","affiliation":[{"name":"Programa de P\u00f3s\u2010Gradua\u00e7\u00e3o em Biodiversidade Animal Universidade Federal de Santa Maria Santa Maria Rio Grande do Sul Brazil"},{"name":"Centro de Apoio \u00e0 Pesquisa Paleontol\u00f3gica da Quarta Col\u00f4nia Universidade Federal de Santa Maria (CAPPA\/UFSM) S\u00e3o Jo\u00e3o do Pol\u00easine Rio Grande do Sul Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4,18]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2002)022[0313:ANSOTT]2.0.CO;2"},{"key":"e_1_2_10_3_1","first-page":"23","article-title":"Early Development of the Mammalian Superficial Masseter Muscle in Cynodonts","volume":"40","author":"Abdala F.","year":"2004","journal-title":"Palaeontologica Africana"},{"key":"e_1_2_10_4_1","first-page":"407","volume-title":"Late Triassic World: Earth in a Time of Transition","author":"Abdala F.","year":"2017"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsames.2020.102884"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2000)020[0501:GCOTCA]2.0.CO;2"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1096-3642.2003.00096.x"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.palaeo.2010.01.011"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.22456\/1807-9806.21740"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1671\/0272-4634(2000)020[0705:GPDFTB]2.0.CO;2"},{"issue":"4","key":"e_1_2_10_11_1","first-page":"619","article-title":"Growth and Life Habits of the Triassic Cynodont Trirachodon, Inferred From Bone Histology","volume":"49","author":"Botha J.","year":"2004","journal-title":"Acta Palaeontologica Polonica"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1475-4983.2005.00447.x"},{"issue":"10","key":"e_1_2_10_13_1","first-page":"441","article-title":"Multivariate Analysis of Diademodontine Crania From South Africa and Zambia","volume":"75","author":"Bradu D.","year":"1979","journal-title":"South African Journal of Science"},{"key":"e_1_2_10_14_1","first-page":"3","article-title":"A Study on the Skeleton of Diademodon","volume":"3","author":"Brink A.
