Cetiosaurs are a species of primitive sauropods that live on beaches and islands.

A cetiosaurus is about 50 feet long and 55,000 pounds, small for a sauropod. They are beachcombers, and their small size might be indicative of a less nourishing diet or reduced risk of predation. They live solitary lives, and most only see other cetiosaurs to mate.

Cetiosaurs use their tails if threatened like their larger kin, and like them can merely crush smaller creatures in their path.

Trample (Ex): A cetiosaurus can literally run over any creatures in its way that are of Huge or smaller size. Creatures trampled must make a Reflex save (DC 24 half) or take 4d8+10 damage. The save DC is Strength-based.

Skills: Cetiosaurs have a +8 racial bonus on Swim checks.
