Saturnaliidae is a family of basal sauropodomorph dinosaurs found in Brazil , Argentina and possibly Zimbabwe.[1] It is not to be confused with Saturnalidae, a family of radiolarian protists.[2]
Classification
In 2010, Martin Ezcurra defined the subfamily Saturnaliinae for the clade containing Saturnalia and Chromogisaurus, which were found to be close relatives in several studies.[1] While they are sometimes found to be a subgroup within the Guaibasauridae,[1] all recent studies have found the saturnaliines to form an independent lineage at the very base of the sauropodomorph family tree.[3][4][5][6][7][8][9] At one point, Agnosphitys was recovered as a possible saturnaliine until it was recovered as a member of Silesauridae in 2017.[10] Langer and colleagues (2019) recovered Pampadromaeus and Panphagia as relatives of Saturnalia and Chromogisaurus, elevating Saturnaliinae to family rank as Saturnaliidae. In that particular paper, they recovered Guaibasaurus as a basal theropod.[11]
Additionally, Eoraptor, Buriolestes, Bagualosaurus and especially Nhandumirim are also possible members of this clade following their position in many recent phylogenetic analyses[4][5][6][7][8][9] and the new definition given by Langer et al. (2019), as "the maximal sauropodomorph clade to encompass Saturnalia but not Plateosaurus."[11] In several of these analyses, Guaibasaurus is recovered as distantly related to Saturnalia, sometimes as a more basal sauropodomorph or saurischian, and in some cases specifically related to more derived taxa such as Macrocollum and Unaysaurus. This way a Guaibasauridae including Saturnalia and kin is no longer being supported.
