In which Argentine geological feature were the *Xenotarsosaurus* fossils primarily discovered?
Answer
Chubut province, within the Bajo Barreal Formation
The limited fossil evidence defining *Xenotarsosaurus bonapartei* originated from a specific geographic and geological location in Argentina. The bones were uncovered in the Chubut province. More precisely, they were recovered from sediments belonging to the Bajo Barreal Formation. Understanding the geological context of the Bajo Barreal Formation is vital, as revisions suggest the dinosaur lived during the Cenomanian to Turonian stages of the Cretaceous Period, placing it within a specific ancient South American ecosystem.
