The Dinosaur Olympics were held every year at the end of summer in Treetown, once the young people who had been learning to live in harmony with dinosaurs had completed their summer youth camp. Participants at the youth camp in Treetown, were entered into the Dinosaur Olympics at the season's end. If they won the Ring Riding Event in Cornucopia they would graduate from the camp, and may choose their habitat — the race comprised four groups consisting of one boy and one girl riding a Deinocheirus running laps around an oval track collecting rings on a poll. Once the race is won, the human pair may choose to serve as a Habitat Partner in the Land, Sea, or Sky.
