Creating exhibits featuring multiple species is important in order to create a thriving park in such a small space. However, knowing the rules of mixed exhibits is also extremely important. Learning and memorizing these rules will mean the difference between a successful 5 star park, and a choatic mess of constant dinosaur breakouts.

I will start by listing the different groups of dinosaurs in the game. Then, I will list the do's and don'ts of mixed exhibits. Finally, there will exceptions that I will list at the end.

Statements that start with 'In general' are mostly true, but have one or two exceptions that I will cover at the end of the guide.

Statements that contain 'always' or 'never' hold true in every situation.

Before we start, it is important that you know the different groups of dinosaurs that you are dealing with. Each group has different behaviors and personalities that will determine how they interact with other groups. Each group will have one or more sub-divisions.

Passive Herbivores - these herbivores have a mild temper and do not fight with carnivores. This group includes three sub-divisions: Hadrosaurs, Ornithomimids, and Ouranosaurus.

Aggressive Herbivores - these herbivores are large, aggressive, and will fight with carnivores if need be. This group has five subdivions: Ceratopsians, Stegosaurs, Ankylosaurs, Pachycephalosaurs and Iguanodon.

Sauropods - this group is large but mostly gentle. They do not fight with carnivores, but their large size means they usually will not get hunted. Only sauropods make up this group.

Small Carnivores - these carnivores are small but extremely fiesty. They can pick a fight with certain herbivores but will ignore others. Velociraptor, Dilophosaurus, and Deinonychus make up with group.

Medium Carnivores - these carnivores are of intermediate size between large and small carnivores. They can be distinguished from large carnivores, because they cannot kill an Iguanodon in one hit.

Large Carnivores - these carnivores are larger and can take on most herbivores. This group includes the large carnivores, and hybrids such as indoraptor and the indominous rex. They can be distinguished from medium carnivores as they can sneak up on and kill an Iguanodon.

1.) In general, all herbivores will get along with one another.

2.) In general, sauropods will get along with carnivores. Their large size usually prevents them from being hunted.

3.) In general, small carnivores and large carnivores can coexist in the same exhibit. The small carnivores will run away from the larger ones, and when fights do happen, the small carnivore will usually run away without any fight. Small and medium carnivores will also usually get along for the same reason.

4.) Small carnivores will always get along with aggressive herbivores. They may square off but there is never any bloodshed.

1.) Small carnivores will never get along with small carnivores of a different species.

2.) Large carnivores will never get along with large carnivores of a different species.

3.) Passive herbivores will never coexist with carnivores of any type. The carnivores will activly hunt the passive herbivores until none remain.

4.) Large and medium carnivores will never coexist with aggressive herbivores. The two sides will square up and fight until one side dies.

People looking for efficiency may go a step further and try to enclose their dinosaurs together based on their maximum population need. Most herbivores can be placed into categories based on their population need, that being low, medium, and high population.

High population herbivores include all of the hadrosaurs, iguanodontids, and ornithomimids, as well as most of the sauropods and a few of the stegosaurs. They generally have a population need of around 20.

Medium population dinosaurs include the rest of the stegosaurs, all of the pachycpehalosaurs, half of the ceratopsians, Euplocephalus and Dreadnaughtus. They generally have a population need of 10-15.

Low population dinosaurs include the rest of the ankylosaurs and ceratopsians. They generally have a population need less than 10.

Herbivores can further be grouped based on their similar paleo diets.

Paleobotany is the process of growing plants that when eaten, can enrich herbivores and improve their life span. A neutral paleobotany need has no positive or negative effects on a dinosaurs health, while a negative paleobotany need will cause a reduced lifespan.

Sauropods can be housed with any other herbivore and still obtain a positive paleobotany need as they have a separate feeder type from the other hebrivores.

For the rest of the herbivores, the following rules are best for efficient paleo feeders.

Hadrosaurs and Iguanodontids should generally be placed together, as they have very similar diets. Ceratopsians and Ornithomimids can be placed in these enclosures as well, but one should be more cautious as to prevent negative paleobotany.

Stegosaurs and Ankylosaurs can eat much of the same plants, along with pachycpehalosaurs. In some cases, Ceratopsians and Ornithomimids can share an enclosure with these three groups of herbivores, but it is much harder to ensure a net positive paleo diet for all of them.

1.) While herbivores will usually get along with one another, the sauropelta and polecanthus are the exceptions to this rule. The sauropelta will never get along with the Gigantspinosaurus, Maiasaura, Muttaburasaurus, Parasaurolophus, Stegosaurus, Stygimoloch, or Tsintaosaurus. The sauropelta has a max population of 4 individuals, while all the listed individuals have a social minimum that is greater than or equal to 4. Therefore, there is no combination of sauropelta and these herbivores that would not result in agitation. Similarly, the polecanthus cannot herd with the muttaburasaurus since its max population is too small for the muttaburasaurus's minimum social need of 6.

2.) While sauropods are usually safe against carnivores, the Indominous rex is the exception to this rule. The I. rex is the only carnivore that can kill a sauropod. Therefore, it is best to keep sauropods out of an I. rex enclosure.

3.) While small carnivores and large carnivores can usually get along just fine, the indoraptor and spinoraptor are exceptions to this rule. Both will fight with any small carnivores in its exhibit until it dies or eliminates them all. Therefore, keep them separate from any small carnivores.

4.) While aggressive herbivores usually ignore small carnivores, the Iguanodon is the exception to this rule. Iguanodon will fight and usually destroy any small carnivores in its territory, so it is unwise to put them together.
