A replica of one of nine 140 million-year-old sauropod dinosaurs that were recently unearthed in the Patagonia region, has been put on display at the Cultural Science Center in Buenos Aires, as seen on Thursday.
The dinosaurs were discovered by a team of paleontologists in a geological formation known as Bajada Colorada. They were subsequently named Bajadasaurus pronuspinax, which is reportedly a nod to the area they were found in, and their appearance. The spine of the dinosaur contains a fearsome row of spikes thought to have been used as a means of defence.
"Bajadasaurus is a herbivorous dinosaur of the large group of sauropods, the long-necked dinosaur and the long and large in general, but Bajadasaurus was a moderate small size of about 9 metres," explained Pablo Gallina, paleontologist and CONICET deputy researcher.
"140 million years ago is what is known as the Lower Cretaceous [geological time period], whose evolution of the dinosaurs, the dinosaurs' fauna — we know nothing about, not only in Argentina but worldwide. Therefore in this way we are completing the knowledge about these dinosaurs," he added.
