The Brave Lizard

Ouranosaurus (meaning "brave (monitor) lizard") was an unusual iguanodont that lived during the early Cretaceous (early Aptian) about 110 million years ago in what is now Africa. Ouranosaurus measured about 7 m (24 ft) long and weighed about 4 tons. Two complete fossils were found in the Echkar (or El Rhaz) Formation, Gadoufaouna deposits, Agadez, Niger, in 1966 and the animal was named in 1976 by French paleontologist Philippe Taquet.
