In the Tamil Nadu province of southern India, a fossilized skeleton belonging to the Dravidosaurus dinosaur was found in the crust layers formed in the Upper Cretaceous.
This prehistoric animal was first described in 1979 by paleontologists P. Yadagiri and K. Ayyasami, being called Dravidosaurus blanfordi.
The grazing giant lived in the Mesozoic era, about 90 million years ago, in the forested regions and near the banks of some rivers.
To ease digestion he used to swallow stomach stones – gastrolites – whose sharp edges squeezed large amounts of plant food.
His earlier limbs, but robust compared to the very muscular backs, moved more square, but if he wanted to reach the branches of the trees to break the tender leaves or if he wanted to monitor the surroundings, he raised himself up to two feet by leaning his body on the tail.
Paleontologists have estimated the length of this dinosaur as 3 m and 1.5 tons. Characteristic of this species was the double row of large plaques, bone on the back, and pairs of thorns that appeared at the end of the tail.
This armored structure protects and worsens the predatory dinosaur, thus preventing any possible attacks. The back plates were covered with highly vascularized skin, which, in case of danger, became reddish, making it look rather scary.
The food was made up of the plants at the ground level and the leaves of the trees that they tore with their toothless mouh and chew them with the weakly developed masses in the back of the jaws.
