 The specimen was collected at the "Hoyada de los esfenodontes" sublocality, part of the main fossiliferous locality of La Buitrera, about 30 km south of the village of El Chocόn.It was recovered from massive red sandstones that form the upper part of the Candeleros Formation of the Rio Limay Subgroup (Cenomanian to Turonian stage), close to its border with the Huincul Formation.It comes from the lower levels of the outcrops in this region, which produces a rich fauna of small vertebrates, including specimens of the large rhynchocephalian "Priosphenodon avelesi", the basal snake "Najash rionegrina", the notosuchian "Araripesuchus buitreraensis", the unenlagiine dromaeosaurid "Buitreraptor gonzalezorum", and also mammals and pterosaurs.
