Small Herbivores > No Carnivores - small herbivores such as Gallimimus or Archaeornithomimus live peacefully with other herbivores, and work well in herds, but do not put them with any size of carnivore or they'll end up as lunch!.All herbivores will mix with each other - be warned though that they all have different needs, so a paddock that works for Triceratops will not work for Brachiosaurs.Here's our general guide to what dinosaurs will tolerate each other, but bear in mind this is not a record of every animal's social needs, nor is it what population will be tolerated - we're talking about dinosaur mixing only, and which dinosaurs can mix with each other.
