Remarkable Facts About Ouranosaurus

Ouranosaurus possessed long neural spines along its backbone, which held a fleshy sail or fat-storing hump. This sail likely helped control body temperature by absorbing solar warmth in the morning and dumping heat during hot afternoons. Its broad snout featured toothless beak edges ideal for clipping leaves along riverbanks.
