Campananeyen is a genus of rebbachisaurid sauropod dinosaur from the Late Cretaceous (Cenomanian) Candeleros Formation of Argentina. The type species is Campananeyen fragilissimus.[1]
Classification
[edit]Campananeyen was entered into a phylogenetic analysis and found to be the sister taxon of Sidersaura, closely related to Zapalasaurus and an unnamed rebbachisaurid from the La Amarga Formation.[1]
Paleoenvironment
[edit]The Candeleros Formation is interpreted as an ancient desert known as the Kokorkom desert, with some oases in it, and its fossils represent a faunal assemblage typical of Middle Cretaceous ecosystems in the western remnants of Gondwana.[2] Other animals from this formation include the rhynchocephalians Tika and Priosphenodon, the snake Najash, the mammal Cronopio dentiacutus, the ornithischian Jakapil, the theropods Alnashetri, Buitreraptor, Ekrixinatosaurus, and Giganotosaurus, as well as the sauropods Andesaurus and Limaysaurus.
