Special Abilities
Stun (Ex) The ankylosaurus's tail can deliver a powerful, stunning blow. A creature struck by this attack must make a DC 23 save or be dazed for 1 round. If the strike is a critical hit and the target fails its save, it is instead stunned for 1d4 rounds. The save DC is Strength-based.
The ankylosaurus is a powerful, squat dinosaur more than capable of defending itself against enemies. Its back is heavily armored with thick bony plates and spikes. A solid blow from an ankylosaurus's tail can leave most creatures stunned long enough for the armored dinosaur to make good an escape, although once confronted, most ankylosauruses are too ill-tempered and stubborn to flee. Instead, they stand their ground and use their tails to great effect in battle. An ankylosaurus is 30 feet long and weighs 6,000 pounds.

As swift and agile as it is deadly, the deinonychus is a pack hunter, running with several of its kind to take down prey and rip it apart with their gutting talons.
You can apply the young simple template to create statistics for smaller, more agile velociraptors. Conversely, you can either increase the deinonychus to Large size and its Hit Dice to 8 or simply apply the giant and advanced simple templates to create a formidable megaraptor.
Long-necked and long-tailed, this large, predatory reptile glides through the water on four powerful flippers.
