Back when the old, old west was still as green as a bristlecone pine and cowboys were as common as warts on a Stegosaurus, one cowboy stood out among all cowboys. With the strength of an Iguanodon and the speed of a Utah Raptor, lasso-tossing, Pleiosaurus-riding Rocky is legendary. There isn?t a dinosaur in the land that would think of giving Rocky a lick of trouble. That is, until he meets T. Rex, the rip-roarin?est, snip-snortin?est, flame-breathin?est reptilian ever to stomp the earth. But Rocky is up to the challenge, and his efforts to tame T. Rex take the disagreeing duo on a Western adventure of epic proportion.
