Bagualia

Pol et al. 2020

Bagualia is an extinct genus of eusauropod dinosaur from the Early Jurassic Cañadón Asfalto Formation in what is now the Chubut Province of Argentina. The type species, B. alba, was formally described in 2020. Bagualia represents the oldest known definitive eusauropod, and due to the completeness of its material, it represents one of the most important taxa for understanding the early evolution of the group.
