"Darius, how would you classify the animals on our right?"

A blue and white boat about thirty meters long was moving placidly on the river. Above it was a group of at least fifty people, most of whom clustered along the right side of the boat.

The person who had asked the question was a woman in her thirties, still very handsome and with a youthful and energetic appearance. She had brown hair combed in a tuft and wore a very large white jumpsuit, suitable for repelling the sun's rays. The other passengers, except for the ship's crew, were dressed more casually, even if many of them seemed to be beginning to regret their stylistic choice because of the heat; none of them seemed to be over twenty.

The guy named Darius was a rather short, very skinny in build dark-skinned guy. He was looking at the herd of dinosaurs ahead of them, placid herbivores with a large crest on their backs and a duck's beak. After a short wait he gave his answer.
