Strophodus jaisalmerensis is the new species of Hybodont Shark (currently extinct) belonging to the Jurassic age. The teeth of the new species was discovered by a team from the Geological Survey of India (GSI) in Jaisalmer, Rajasthan. The specimen is estimated to be 160-168 million years old.
With this discovery, the genus Strophodus is discovered for the first time in the Indian subcontinent. It is only third such discovery from Asia after Japan and Thailand. Hybodont Sharks dominated both marine and fluvial environments during the Triassic and early Jurassic times. They became extinct by the end of the Cretaceous period.
