The research plan presented herein includes the laboratory preparation of the syntypes of Saturnalia tupiniquim as well as the description of new pectoral and pelvic skeletal elements of this sauropodomorph. At the same time, a new Dinosauromorpha specimen, tentatively considered as a S. tupiniquim juvenile, which was recently unearthed at the site "Cerro Alemoa", Santa Maria Formation, will be described. The material includes vertebrae, a nearly complete right ilium, in addition to a femur, tibia, fibula, metatarsals and phalanges of the right limb. The dataset obtained from the descriptions will be included in a comparative study in order to investigate possible morphological variations between the new specimen and the syntypes of S. tupiniquim. Subsequently, it will be verified whether these specimens should be assigned to S. tupiniquim or congregate a greater taxonomic diversity. In turn, the anatomical variations identified between these specimens will serve as parameters for a broader taxonomic revision of the Carnian sauropodomorphs, assessing possible cases of synonymy between them. Finally, a phylogenetic study will be developed, encompassing not only the sauropodomorphs, but the basal Saurischia as a whole. This more inclusive analysis is justified by the many uncertainties that still surround the relationships among the Neotriassic Sauropodomorpha of the South America, e.g. Eoraptor and Guaibasaurus, which have been alternatively considered as basal saurischians or theropods.
