I was looking at the Bestiary 2 for dinosaurs, becuase dinosaurs, and saw that the Tylosaurus is a Gargantuan creature with a space of 15 ft (Huge). I was wondering which one is correct, or if that is the correct numbers and that the size is for modifiers.
The PRD entry also seems to be in error. The size penalty to attacks and AC are conducive of a gargantuan creature, so either the space/reach is in error or the penalties are.
Well considering that an actual Tylosaurus proriger was roughly iirc about 15 meters in length, I'm pretty sure it's supposed to be a gargantuan creature in game.
