Dinosaur, Tyrannosaurus Rex

Tyrannosaurus Rex
Life restoration of feathered 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.

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.


A tyrannosaurus has a +2 racial bonus on Listen and Spot checks
