Ouranosaurus nigeriensis was an unusual hadrosauroid that lived during the early Cretaceous about 110 million years ago in what is now Africa.
Ouranosaurus measured about 7 meters long (24 ft) and weighed about 4 tons.
It had a hump, resembling that of a bison or camel, used as a source of nutrition during harsh conditions.
There were a number of bumps running from the nasal opening to the top of the skull, they may have been used for socialisation and mating displays.
