It consisted of hip bones, a leg bone, a shin bone, tail bones, and the bone of a forearm. Unfortunately, fossil remains were lost. The huge-bodied lizard is among the largest dinosaurs. Bones of the dinosaur were mistaken as pieces of petrified wood.

This dinosaur with a massive body size inhabited woodlands and grasslands of India. Paleontologists suggested that the dinosaur was a mobile animal and would move around various lands.

Who did a Bruhathkayosaurus live with?

Bruhathkayosaurus Fun Facts

What did a Bruhathkayosaurus look like?

The Bruhathkayosaurus is classified as one of the largest dinosaurs due to its massive body size. The length of the tibia is computed to be 7.8 ft (2.4 m) more than the length of the tibia of the Argentinosaurus, one of the largest dinosaurs that ever existed. While remains of fossils discovered were swept away and lost in a monsoon, characteristics of original fossils are only in the form of line drawings. There are no diagnostic characteristics described from original remains of the huge-bodied lizard. While the description based on the specimen of the hip bone, the leg bone, and other bones is unavailable, characteristics including the size, the length, and the weight of the dinosaur are estimated using line drawings of the specimen. It was a long-necked dinosaur with a long tail. Its length is not known. The dinosaur is thought to have had a blue-gray pelage.
