Jeyawati is a Hadrosauroid dinosaur known from the Moreno Hill Formation in New Mexico. It dates back to about 91 million years ago, in the Turonian age of the Late Cretaceous. It is known from fairly scattered remains of an adult individual from both the skull and the postcranial skeleton. It was found to be a fairly derived Hadrosauroid, helping to place the migration of the group from Asia to North America in a broader phylogenetic context. It had strangely long and sloping face that might indicate it had a different diet or feeding style than other Hadrosauroids. It may have had keratinous ornamentation on his head, allowing for visual display between members of the species.
