In Primal Prey, the Styracosaurus is available to hunt early on, and is the first dangerous herbivore available to hunt (chronologically). They almost always travel in herds unless wounded, and the herds have a nasty habit of gathering around the entry portal. A Styracosaurus can weigh anywhere from 5,100 to 6,500 lbs. They are common targets for utahraptor and tyrannosaurus. They can often be found by lambeosaurus and occasionally triceratops.
