Isisaurus is a member of the sauropod family. It was a herbivore. It was named after the Indian Statistical Institute. It could grow to be as long as 69 ft and is related to Titanosaurus, but with various advancements. It has a long, thick neck and is located in India.

Discovery and naming[]

The holotype specimen of Isisaurus, ISI R 335/1-65, was described by Sohan Lal Jain and Saswati Bandyopadhyay in 1997, though it was initially named Titanosaurus colberti. The specific name honoured Edwin Harris Colbet, a distinguished American palaeontologist. As the genus Titanosaurus is dubious, Wilson and Upchurch reclassified it as a distinct genus in 2003.


Isisaurus is a kind of dinosaur genus existed in the late Cretaceous period. It is believed that those species are the inhabitants of current India. Isisaurus belongs to the group of sauropod. This herbivore species comes under the classification of Chordata, Reptila, Dinosauria, Sauropodomorpha, Sauropoda, Titanosauria, Antarctosauridae.

Sohan Lal Jain and Saswati Bandyopadhyay were the first to name this type specimen Isisaurus colberti, ISI R 335/1-65 as Titanosaurus colberti, 1997. The specimen Isisaurus colberti, has been named after Edwin Harris Colbert. But later in 2003, it has been placed in its own genus, by Wilson and Upchurch. This is because the genus had a strange appearance with a short, vertical directed neck and long forelimbs, the structure making it different from rest of the sauropods.

Researches revealed that the humerus of the specimen was 148 centimetres long and hence it is predicted that the Isisaurus would have grown to about 18 meters length and weighed about 14,000 kg. The type of dinosaur has been considered as the most unique one among the sauropods as it has a different inbuilt skeletal system having its radius and ulna far shorter than its humerus with shortened and tall cervicals.
