A gorgosaurus is a smaller, leaner relative of the famous tyrannosaurus.
Gorgosaurs are about 30 feet in length and weigh 2-3 tons. Unlike the tyrannosaurus, which occasionally hunts in pairs, the gorgosaurus is a solitary beast. They are unusually specialized, as most of their nourishment comes from stealing the kills of other animals, such as dinonychus packs or even human hunters. They are still capable of hunting, however, and usually target young and infirm lambeosaurs and anatotitans when they do.
Combat
Gorgosaurs are reckless combatants, grabbing and swallowing smaller creatures until all are dead or the rest flee. Against equal sized creatures, they attempt to drag them to the ground and consume them alive.
Improved Grab (Ex): In order to use this ability, a gorgosaurus must hit with a bite attack. If it hits, it can make a grapple check as a free action without provoking an attack of opportunity. If it gets a hold, it deals automatic bite damage each round and can swallow its opponent whole.
Swallow Whole (Ex): By making a successful grapple check, a gorgosaurus may swallow a held foe at least one size smaller than itself whole. Once swallowed, a victim takes 2d8+8 points of bludgeoning damage plus 8 acid damage every round until it escapes or dies. A successful grapple check allows the creature to climb out of the stomach and into the gorgosaurus? mouth, where another grapple check is required to get free. Alternatively, the swallowed creature can escape by cutting its way out with either claws or a light slashing or piecing weapon. Dealing at least 30 points of damage (AC 12) in this fashion allows the creature to escape. Once a single swallowed creature exits, muscular action closes the whole; another swallowed creature must cut its way out as well. A gorgosaurus? stomach can hold 2 Medium-sized, 8 Small, 32 Tiny or 128 Diminutive or smaller creatures.
Skills: A gorgosaurus receives a +2 racial bonus on all Listen and Spot checks.
