A herbivorous dinosaur that fended off predators with a row of spines running along its back and lived 140 million years ago has been found in Argentine Patagonia.

The discovery of the new species of dicraeosauridae, christened Bajadasaurus pronuspinax, was revealed in scientific journal Nature.

A reproduction of its spiny neck was exhibited in the Cultural Science Center in Buenos Aires.

"We believe that the long and sharp spines -- very long and thin -- on the neck and back of Bajadasaurus and Amargasaurus cazaui (another dicraeosauridae) must have been to deter possible predators," said Pablo Gallina, an assistant researcher at the state council of scientific and technical investigations (CONICET) and Maimonides University.

"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," he added.

1. Badass Dinosaur With a 'Mohawk' of Spikes Uncovered in Patagonia


When dinosaurs roamed the Earth in ancient Patagonia, one particular type of dinosaur might have stuck out amongst the rest.

Living 140 million years ago in the early Lower Cretaceous, the newly discovered herbivore Bajadasaurus pronuspinax had a thing for growing spikes.

It was part of the Sauropod family, but looked a little like a small Brontosaurus crossed with a porcupine.

"The sauropods are the big dinosaurs with long necks and long tails, but specifically this is a small family within the sauropods which were about 9 or 10 metres in length," palaeontologist Pablo Gallina from the National Scientific and Technical Research Council in Argentina told Agencia EFE.
