Dinosaur, Tyrannosaurus Rex

This ravenous creature is the most fearsome of all carnivorous dinosaurs. It eats almost anything it can sink its teeth into and spends a great deal of its time scavenging for carrion and chasing smaller carnivores away from their kills.
Despite its enormous size and 6-ton weight, a tyrannosaurus is a swift runner. Its head is nearly 6 feet long, and its teeth are from 3 to 6 inches in length. It is slightly more than 30 feet long from nose to tail.

Combat
A tyrannosaurus pursues and eats just about anything it sees. Its tactics are simple’-“charge in and bite”
Improved Grab (Ex) : To use this ability, a tyrannosaurus must hit an opponent of up to one size smaller with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe the following round.
Swallow Whole (Ex) : A tyrannosaurus can try to swallow a grabbed opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 2d8+8 points of bludgeoning damage and 8 points of acid damage per round from the tyrannosaurus’s gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the gizzard (AC 12). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.
A Huge tyrannosaurus’s gizzard can hold 2 Medium, 8 Small, 32 Tiny, or 128 Diminutive or smaller opponents.
