This creature resembles nothing so much as a reptilian rhinoceros, its head and  neck are protected by a bony shield and its skin is very thick.

The monoclonius is a species of ceratopsian, the most famous of which is the triceratops.

These dinosaurs are around 15 feet long and very strong, but the species are inoffensive and herbivorous. Most monoclonius live in family units with an alpha male and multiple females, as well as the alpha’s various offspring. Unlike triceratops, they are not particularly territorial or aggressive.

COMBAT

If they or their offspring are threatened, a herd of monoclonius will charge the offending predator, impaling it on their powerful horns. They usually retreat if a fight goes badly, but a mother monoclonius will defend her child to the death.

Powerful Charge (Ex): When a monoclonius charges, its gore attack deals 4d6+14 points of damage.

Trample (Ex): A monoclonius can literally run over any creatures in its way that are of Medium or smaller size. Creatures trampled must make a Reflex save (DC 21 half) or take 2d6+10 damage. The save DC is Strength-based.
