Ouranosaurus Beneath the Sun
Positioned in side view, Ouranosaurus displays a high sail stretching along its back spine while absorbing heat from the sun above. Its duck-billed jaw and sturdy limbs ground the creature in an open landscape.
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.
