A new species of a herbivorous dinosaur that lived over 140 million years ago was found in Argentine Patagonia.
The new species’ name Bajadasaurus is a combination of Spanish, Greek, and Latin meaning “lizard from Bajada with forward-bending spines”.
The dinosaur’s most remarkable feature is a row of long and sharp spikes protruding from his neck. Scientists believe the possible purpose of the spikes was to deter predacious animals. According to Pablo Gallina, a paleontologist who first discovered the remains of the dinosaur in 2010,
Bajadasaurus’s structure was very fragile and could have been easily broken or fractured.
A reproduction of Bajadasaurus spiky neck was exhibited in the Cultural Science Center in Buenos Aires, Argentina.
The dinosaur is a member of a unique family of dinosaurs with spiky backbone, the first of which was found in Tanzania over 100 years ago.
