“Kentrosaurus: The Spiky Dinosaur That Broke All the Rules!”
The Kentrosaurus is a small, herbivorous dinosaur that measures around 13 feet in length and stands about 4 feet tall at the hips. It features a distinctive appearance characterized by rows of sharp, long spikes extending from its back and tail. This dinosaur boasts a compact build with a low-slung body and sturdy legs, making it well-suited for a life on the move in its prehistoric environment. Its hide is adorned with scales, providing it with some protection against potential predators.
With a relatively small head and a beak-like mouth, the Kentrosaurus primarily feeds on low-lying vegetation such as ferns, shrubs, and cycads. Its eyes are positioned on the sides of its head, granting it a decent field of vision, and its relatively long neck enables it to reach for plant material with ease.
Kentrosaurus moves on all fours and is known for its remarkable defense mechanism—the clusters of formidable spikes that extend along its back and tail. These spikes serve as an effective deterrent against potential threats, deterring predators from getting too close. Additionally, Kentrosaurus possesses keen reflexes and can use its tail to defend itself if cornered, making it a formidable opponent even for larger predators that might attempt to prey on it.

Kentrosaurs are related to Stegosaurs, but are usually only 10 – 16 feet long and weigh 2,000 lbs. They are docile herbivores, browsing through jungles and scrub forests in small herds. If provoked, however, they are deadly, lashing out with their spiked tails and shoulder spines.

COMBAT
If threatened, a kentrosaurus will assume a defensive position, always keeping its tail facing its enemies. If their offspring are threatened, the adults of a herd will form a protective circle around their young, tails out.
Augmented Critical (Ex): The spikes on the tail of a kentrosaurus are keen and as sharp as picks. They threaten a critical hit on a 19-20 and deal x4damage on a successful critical hit.
Reflexive Attack (Ex): Once per round, a kentrosaurus may make an immediate melee attack with its shoulder spine against any creature that damages it in melee. Attack bonus +7, damage 1d8+3.
Spiny Defense (Ex): Any creature that hits a kentrosaurus in melee using a handheld or natural weapon (but not a reach weapon) must succeed on a DC 15 Reflex save or take 1d6+7 points of damage from the creature’s broad spines. The save DC is Dexterity-based.
