  Genus Ouranosaurus
Ouranosaurus was a plant-eating dinosaur that lived in the early Cretaceous period, about 115 to 100 million years ago. Its fossils have been found in Niger in Africa, and its name, which means "brave monitor lizard" was chosen by the French paleontologist, Philippe-Taquet in 1976.

Ouranosaurus was 23 feet (7 meters) long, and probably weighed around 4 tons.

Ouranosaurus has long thick spines on its back and tail, and for many years scientists believed that these supported a large fin (sometimes also called "sail") that was covered with skin, similar to the fin found on Spinosaurus. It was thought that this fin was probably used for temperature regulation: the animal could face it towards or away from the sun, depending on whether it needed to heat up or cool down.

Close examination of Ouranosaurus however suggests that whatever was on its back may have been quite different from the fin on Spinosaurus. In fact, many scientists now believe that the spines on Ouranosaurus back are more likely to have supported a hump (similar to a modern bison's hump) than a sail. If this was the case, the hump may perhaps have been used to store food and water (like a camel's hump).
