Indosaurus, scientifically known as "Indosaurus matleyi," is classified as a member of the Theropoda group, specifically belonging to the Abelisauridae family. The name "Indosaurus" is derived from its geographical origin in the Indian subcontinent, and it lived during the Late Cretaceous period, approximately 70 to 65 million years ago.

The discovery of Indosaurus fossils is primarily based on fragmentary remains found in India, making it a rare and valuable contribution to our understanding of dinosaur diversity in this region.

As a theropod dinosaur, Indosaurus was a carnivorous predator with a bipedal stance. Unfortunately, the limited fossil evidence makes it challenging to fully reconstruct its complete physical appearance. However, based on related abelisaurid dinosaurs, it is likely that Indosaurus had a robust body with strong, muscular hind limbs and smaller, functional forelimbs. Its head was equipped with sharp teeth, enabling it to effectively grasp and tear apart its prey.

Indosaurus' cranium hints at the possibility of having horns above its eyes, but regrettably, all the fossil evidence supporting this feature has been lost. There is a potential connection between Indosaurus and the unique Madagascan dinosaur, Majungasaurus.

The size of Indosaurus is also subject to speculation due to the lack of complete remains, but estimates suggest it may have reached lengths of around 20 to 25 feet (6 to 8 meters), making it a medium-sized theropod.
