Consequently, the study of holomorphic specimens provides crucial information to reassess existing phylogenetic and taxonomic interpretations. The extinct Mesozoic shark genus †<i>Sphenodus</i> exemplifies these challenges. Initially classified based on dental traits, the genus has undergone multiple revisions, reflecting its taxonomic instability. However, the presence of skeletal remains assigned to †'<i>Sphenodus</i>' <i>macer</i> and †'<i>S</i>.' <i>nitidus</i> provides an opportunity to re-evaluate the phylogenetic and taxonomic relations of this genus. In this study, we critically reviewed the systematics and taxonomic relationships of †<i>Sphenodus</i>, through an exhaustive literature review and comparison with previous phylogenetic hypotheses. Our analysis of skeletal characters suggests the synonymy of †<i>S. macer</i> and †<i>S. nitidus</i> and supports previous Hexanchiformes classifications for the genus, placing it in a close relation to †<i>Notidanoides</i> forming a clade in sister relation to Hexanchidae. However, the teeth originally used to define †<i>Sphenodus</i> lack diagnostic traits for taxonomic identification, rendering†'<i>Sphenodus</i>' a <i>nomen dubium</i>. Consequently, we introduce a new name, †<i>Archaeogracilidens</i>, to include the species based on skeletal material and that present teeth with a well-preserved root and a crown, establishing a more stable systematic framework for this group.</p>","PeriodicalId":50028,"journal":{"name":"Journal of Systematic Palaeontology","volume":"23 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7617882/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
