A mosasaur swims calmly through an aquatic scene defined by gentle waves near the surface. Its long snout, paddle-shaped limbs, and strong muscular tail propel the large sea reptile forward.
Life of the Ocean Mosasaur
Mosasaurs were fully aquatic reptiles that breathed air but spent their entire lives in open marine waters. They evolved powerful tail flukes and paddle-like flippers to navigate ancient seas with speed and control.
