Saturnaliinae is a clade (or subfamily) of sauropodomorph dinosaurs belonging to the Guaibasauridae found in Brazil and Argentina.[1]
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] other studies have found the saturnaliines to form an independent lineage at the very base of the sauropodomorph family tree.[2] At one point, Agnosphitys was recovered as a possible saturnaliine until it was reclassified into the Silesauridae in 2017.[3] Langer and colleagues (2019) recovered Pampadromaeus and Panphagia as relatives of Saturnalia and Chromogisaurus, elevating Saturnaliinae to family rank as Saturnaliidae. They recovered Guaibasaurus as a basal theropod.[4]
