A new species of Dinosaur that lived some 140 million years ago has been discovered by paleontologists in Argentina.
The fossilized remains were discovered in Patagonia and suggest this species of Dinosaur had an astonishing backbone with extremely sharp and long spikes.
Named ‘Bajadasaurus pronuspinax’, the creature is thought to have lived 140 million years ago.
Researchers say that it exhibits the most extreme form of the backbone spikes.
The dinosaur was most likely a herbivore and roamed the Earth during the beginning of the Cretaceous period.
Experts argue that the dinosaur was covered by thick sheaths that gave the creature’s spikes a ‘horn-like functionality, that may have served both as an offensive and defensive feature, but as well as make male dinosaurs more sexually alluring.
Furthermore, the extension on the back of the dinosaur may have helped it regulate body temperature.
Scientist s further theorize that the massive spikes may have a fleshy hump between the spines that served to store reserves, just like in camels.
Speaking about the recently-discovered dinosaur, Pablo Gallina, a scientist from the National Scientific and Technical Research Council explained:
“These spines must have been covered by a keratin sheath similar to what happens in the horns of many mammals. We think that had they been just bare bone structures or covered only by skin, they could have been easily broken or fractured with a blow or when being attacked by other animals.”
Paleontologists argue that Bajadasaurus pronuspinax belonged to the family of wider sauropods group of dinosaurs which were characterized by long necks, small heads, and long tails.
A replica of the Bajadasaurus fossils is currently on display at the Cultural Science Centre in Buenos Aires.
