You are in the floodplains of North Africa, 113 million years ago.

The heat haze shimmered over the damp sandbanks of the river valley, casting a distorted, liquid dreamscape. A small herd of Ouranosaurus—perhaps a dozen adults and several smaller juveniles—foraged in the lush vegetation bordering the waterway. They walked comfortably on all fours, their hoof-like digits leaving deep, satisfying impressions in the mud, occasionally shifting to a bipedal gait to reach high, leafy branches with their elongated, duck-like beaks.

The sun hit the distinctive sails of the herd, running from their shoulders to their tails, making them look like a collection of bipedal ships sailing through the ferns.
