Rigel is a Dryosaurus altus who is afraid of... well, damn near everything. The only creatures he really trusts are herbivores.
He saw his entire family get eaten by an allosaurus fragilus, and he lives under the dilusion that if he were ever to touch a foot to the ground, he would swiftly and promptly be carried off by a predator, torn in half, and eaten. This fear is somewhat justified, considering that Dryosaurs have no natural defenses against big theropods, besides their speed.
He rides on Clay's back for protection.
