Puertasaurus has very few skeletons, as shown in the picture, but it is one of the largest dinosaurs ever discovered.
Puertasaurus has only four vertebrae, but even these fragmented remains suggest that this dinosaur was one of the largest titanosaurs. The discovered dorsal vertebrae are among the widest of all known sauropods, indicating that it had an exceptionally wide thoracic cavity.
Puertasaurus lived during the Late Cretaceous period, approximately 76-70 million years ago. Fossils of this animal were discovered in southwestern Patagonia, Argentina.
