A new diplodocine sauropod from the Morrison Formation, Wyoming, USADiplodocinaeMorrison Formationnew genusnew speciessauropodWyomingPalaeontologyPublisher Copyright: © October 2024 Palaeontological Association.The Morrison Formation of the western United States is well-known for its high diversity of sauropod dinosaurs. The Howe-Stephens Quarry in northern Wyoming is one of several quarries which has yielded several associated to completely articulated dinosaur specimens, among which a semi-articulated diplodocid specimen, MAB011899, which was excavated in 1993. This diplodocid specimen is represented by posterior cervical, dorsal, sacral, and anterior caudal vertebrae, multiple thoracic ribs, two chevrons, a left coracoid, a left ilium, both pubes and ischia, a left femur, a left tibia, and a left fibula. Through comparative anatomy, we interpret this specimen as a new species of diplodocine sauropod, Ardetosaurus viator gen. et sp. nov. Unambigu-ous autapomorphies include paired accessory laminae in the spinoprezygapophyseal fossae of posterior cervical and anterior dorsal vertebrae, bifurcating anterior centrodi-apophyseal laminae in the anterior dorsal vertebrae, fossae present in the centropost-zygapophyseal laminae of the second dorsal vertebra, a low vertebral height/centrum length ratio of the posterior dorsal vertebrae and reduced to absent centroprezyga-pophyseal laminae in the anterior caudal vertebrae. Local autapomorphic features include single centroprezygapophyseal laminae in the posterior cervical vertebrae and a highly elliptical cross-section of the femoral midshaft. Ardetosaurus viator is the first skeletally mature sauropod specimen described from the Howe-Stephens Quarry. This specimen provides insight into serial variation of vertebral laminae and laminar transitions. Finally, the peculiar morphology of the-often not preserved-first chevron is described in detail, and its possible use in studying sexual dimorphism in sauropods is discussed.GeoBioTec - Geobiociências, Geoengenharias e GeotecnologiasRUNvan der Linden, Tom T.P.Tschopp, EmanuelSookias, Roland B.Wallaard, Jonathan J.W.Holwerda, Femke M.Schulp, Anne S.2025-02-25T23:23:30Z20242024-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/octet-streamhttp://hdl.handle.net/10362/179831eng1094-8074PURE: 107716265https://doi.org/10.26879/1380info:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2025-03-03T01:39:19Zoai:run.unl.pt:10362/179831Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-29T00:07:04.446252Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse |
