The beast leaps from behind the rock and onto the poor sauropod. It rips and tears the creatures neck apart with a familiar ease and savagry. You can’t help but see the likes of another massive predator.

The Stokesosaurus is the earliest known relative of the Tyranosaurus Rex. It is about 13ft and stands about 5ft high at the hip. It follows the same attack pattern as the creatures that will arise.

Bite, rip, tear, swallow, repeat. That’s the simple tactics of this great beast.

Improved Grab (Ex) If a Stokesosaurus bites an opponent, it may initiate a grapple as a free action without provoking attacks of opportunity.

Swallow Whole (Ex) If a Stokesosaurus begins its turn with an opponent held in its mouth (see Improved Grab), it can attempt a new grapple check. If it succeeds, it swallows its prey, and the opponent takes bite damage. It can swallow opponents of up to Small size. It can hold 1 small, or 2 tiny or smaller creatures in its stomache at a time. A swallowed creature can try to cut its way free with any light slashing or piercing weapon ( 12 points to cut out), or it can just try to escape the grapple. The Armor Class of the interior of a Stokesosaurs that swallows whole is 12. If the swallowed creature escapes the grapple, success puts it back in the attacker’s mouth, where it may be bitten or swallowed again.


Even though it is an intelligent creature, a Stokesosaurus needs training before it can bear a rider in combat. To be trained, a Stokesosaurus must have a friendly attitude toward the trainer (this can be achieved through a successful Diplomacy check). Stokesosaurus can only be trained as young, because they grow extremely self-centered and aggressive as they mature. Even as young, they are very hard to train and their natural instincts often lead to a trainer suffering many wounds. Six weeks of work and a DC 23 Handle Animal check are required to complete training. Riding a Stokesosaurus requires an exotic saddle. Stokesosaurus eggs are worth about 1,300 gp each on the open market, while young are worth 2,000 gp per baby. They are often more expensive for the risk involved in taking them. Professional trainers charge 1,000 gp to rear and train a Stokesosaurus. They can also serve as special mounts or animal companions, but at a -6 penalty to effective level.
