Abstract A new fauna of cirripedes is described from the Cretaceous (Albian and Cenomanian) of northeastern Texas and southern Oklahoma. This includes 14 species assigned to nine genera, included in the families Zeugmatolepadidae Newman, 1996, Scalpellidae Pilsbry, 1907, Cretiscalpellidae Buckeridge, 1983 and Stramentidae Withers, 1920. New taxa include Texaslepas holterhoffi gen. nov., sp. nov., Jagtscalpellum luteorum sp. nov., Ivolepas worthensis sp. nov., Diotascalpellum acies sp. nov., Arcuatoscalpellum wacoensis sp. nov., Virgiscalpellum marysensis sp. nov., V. rugosum sp. nov., Angulotergum robustum sp. nov., A. kiamichensis sp. nov., A. milviformis sp. nov., Loriculina fragila sp. nov. and L. rubrifluvia sp. nov. All species are small; the material was obtained by washing large bulk samples. The faunas are dominated by stramentids, which were predominantly epizoans that attached to shells of live ammonites. Benthic taxa are generally less common, but equally diverse.

来自美国德克萨斯州和俄克拉荷马州的白垩纪(Albian 和 Cenomanian)的卷足类(胸、甲壳类)

摘要 描述了德克萨斯州东北部和俄克拉荷马州南部白垩纪(阿尔比阶和塞诺曼阶)的卷足类新动物群。这包括分配给 9 个属的 14 个物种,包括在 1996 年的 Zeugmatolepadidae Newman、1907 年的 Scalpellidae Pilsbry、1983 年的 Cretiscalpellidae Buckeridge 和 1920 年的 Stramentidae Withers 中。新分类群包括 Texaslepas holterhoffi gen。十一月,sp。十一月,Jagtscalpellum luteorum sp。十一月,Ivolepasworthensis sp。十一月,Diotascalpellum acies sp。十一月,Arcuatoscalpellum wacoensis sp. 十一月,Virgiscalpellum marysensis sp. nov., V. rugosum sp. 十一月,粗壮的Angulotergum sp。nov., A. kiamichensis sp. nov., A. milviformis sp. 十一月,Loriculina fragila sp. 十一月 和 L. rubrifluvia sp。十一月 所有物种都很小;该材料是通过洗涤大块样品获得的。动物群以链球菌为主,它们主要是附着在活菊石壳上的表皮动物。底栖类群通常不太常见,但同样多样化。
