In Oman, the creation of increased accommodation space (ca. 40 m) is observed relative to Jordan commencing in the interval between the MCE 1 and OAE 2.

Based on a broad survey, the fossil family Petroperlidae Sroka, Staniczek &amp; Kondratieff, 2018 is herein considered as a subfamily (Petroperlinae stat. nov.) within Peltoperlidae; and the subfamily Borisoperlinae Chen and Xu, 2020 syn. nov. is synonymized with Petroperlinae stat. nov. The diagnostic characters of all genera of Petroperlinae stat. nov. are revised and summarized. In addition, two new petroperline stoneflies, <em>Graciloperla bulbosa</em> gen. et sp. nov. and <em>Graciloperla stylata</em> gen. et sp. nov., are described based on male adults, which exhibit well-preserved aedeagal structures, the first known for fossil Peltoperlidae.</div></div>","PeriodicalId":55207,"journal":{"name":"Cretaceous Research","volume":"177 ","pages":"Article 106206"},"PeriodicalIF":1.7,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144864882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
