SRD:Deinonychus

Deinonychus
A deinonychus is bright green along its back and flanks, with a much lighter shade of the same color on its underside. The body has darker spots or stripes. Its tail extends straight out behind itself, held aloft by an intricate structure of bony supports, thus allowing its weight to be carried entirely by the back legs. It weighs about 600 pounds.

Combat
A deinonychus uses a combination of speed, grasping forearms, large teeth, and hind legs with ripping talons. It hunts by running at prey, leaping, and ripping with its rear talons as it claws and bites. The talons count as one attack. A deinonychus has a relatively large brain for a dinosaur, and its pack hunts with cunning tactics.

Pounce (Ex): If a deinonychus charges, it can make a full attack.

Skills: A deinonychus has a +8 racial bonus on Hide, Jump, Listen, Spot, and Survival checks.
