Dinosaur, Lexovisaurus

The tree splinters into pieces as your pursuer smacks it with that long, spiked tail. You made the mistake of disturbing its nest and now its trying to drive you away from its offspring, just as any good parent would. It looks like a small Stegosaur, but has spikes protruding from the sides of its legs.

At a length of 15-18 feet, Lexovisaurus is a smaller member of the Stegosaur family. They are magnificent beasts to look at and are every bit as good of parents as their larger relatives. They lived near the end of the Jurrassic period, as the Stegosaur family was beginning to die out. They will often travel in mixed herds of other Stegosaurs.

Combat

While it rarly attacks for no reason, if threatened, a Lexovisaurus will fight with all the ferocity of an enraged carnosaur and is every bit as dangerous. While they are significantly smaller than other creatures, they will stand up to just about any challenge. Whether this is because of bravery or stupidity is up for Speculation.

Powerful Charge (Ex) Prone to aggressive attacks, a Lexovisaurus will charge into battle and attempt to impale opponents on its shoulder spikes. In addition to all the normal benefits and hazards of a charge, this tactic allows for a single Gore attack at a +9 bonus that deals 3d6 +7 points of damage.

Trample (Ex) While smaller, a Lexovisaurus can still trample opponents of two sizes or smaller into the ground. They deal 1d8+7 points of damage with a DC 17 for half damage.

Animal Companions

Lexovisaurus is perfectly willing to serve as an animal companion as long as the offeror has not caused any harm to its family. They are counted as being 4 levels lower than normal for the purposes of benefits. Keep in mind that they need to eat A LOT of their day.
