Iguanodons are adaptable and highly successful dinosaurs that grow roughly 30 ft. long and weigh five or six tons. They stoop low or crawl to browse on ferns and other low-growing plants, but otherwise walk on their hind limbs.
Iguanodons are generally peaceful herd animals, but are best kept at a distance owing to the readiness with which they defend themselves against perceived threats. An iguanodon uses its "thumb spikes" (which are not actually digits at all) to jab at the head and neck of an opponent.
Trample (Ex): Reflex half DC 25. The save DC is Strength-based.
Skills*: Iguanodons have a +8 racial Hide bonus amongst dense foliage.
