Titanosaur

Titanosaur belongs to the sauropod group. It is a humongous plant-eating lizard with long neck and tail. These animals are said to be the largest to walk on Earth. A recently discovered 20-meter Ninjatitan zapatai may be the oldest titanosaur to be ever discovered. It was found in the Neuquen province of southwest Argentina in 2014. It may have lived approximately 140 million years ago at the initial stages of Cretaceous period.
