Hi there!I am not studying dinosaurs anymore. Only pterosaurs. But I am interested to know the current status of the Triassic archosaur Spondylosoma absconditum from the Santa Maria Formation of South Brazil?There is any new resolution about its taxonomic vality?The name is valid or it represents one composite?Spondylosoma is a dinosaur, a rauisuchian or any other archosaur?The redescription of Teleocrater (Nesbitt, 2017) revealed numerous similarities between Spondylosoma and a few other Triassic taxa leading to their referral to a new clade of archosaurs.Please, let me know about the literature about basal dinosaurs. I am lost in that topic.In 2013, me and Jaime Headden did a preliminary reconstruction, Which is available hereÂhttps://en.wikipedia.org/wiki/Spondylosoma#/media/File: Spondylosoma_skeletal_Headden. png Obviously the reconstruction is not definitive and needs update.---Reference:Nesbitt et al. 2017.
