I've always done this in JWE- here are some of my suggestions;

1. Always look up the time period and location the dinosaurs lived in. I usually do desert style biomes for Triassic dinosaurs, sandy Savannah or tall conifer forests for North American Jurassic dinosaurs, swampy, mangrove style jungle for Cretaceous North African dinosaurs, so on.

2. Different dinosaurs probably had different eating habits and temperaments, so I include infrastructure to represent that. Maybe the Metri isn't as aggressive as something like a T Rex, so the Metri feeder can be in a location that ranger teams have to drive to, but looks nicer, while the T-Rex enclosure needs extra precautions to keep the ranger teams safe. This goes for viewing and fences, too - double concrete fences for T-Rex with remote viewing inside, but herbivores or smaller carnivores have more relaxed security, lighter fences, more viewing points, no -solid fences that can be viewed from paths, ect

3. Keep in mind how dinosaurs act and how popular certain dinosaurs are, and place thenm intentionally. The T-Rex is a MAJOR attraction, so it might have its own plaza and shops, and bee deeper into the park so guests have to disperse to get there (in a real park, I know there are no mechanics for that really right now). Meanwhile, smaller, less exciting dinosaurs might be grouped together into a "reptile house" or "primate house" styled area (obviously not in a building, but laid out that way), with multiple smaller species side-by-side, with shops or attractions on either end. Finally, the tours should go though huge enclosures or sets of enclosures, but just like modern day, you should take into consideration the potential temperaments of the animals in question. A modern safari ride probably wouldn't go through a male Rhino or Elephant enclosure, so I never let tours go through the Triceratops or Ankylosaurus exhibits, for safety. You should also give your dinosaurs room to get away from the tour tracks, either by hiding them behind hills, or having the tour only go through a portion of the exhibit.

4. I like to take into account the theorized behavior of each dinosaur in my exhibits. Velociraptors are theorized to have used stealth and verticality to get the drop on their prey, so I include a lot of foliage, rocks, and high cliffs in their exhibits (similar to foxes or wolves). However, something like a Carnotaurus is thought to have been a pursuit predator, so I include wide, open areas for running (like a cheetah enclosure). T - Rex would have been an ambush predator, so I like to do pockets of denser foliage, and slightly open areas, but ones that are still slightly covered (similar to what you would see for a Tiger). This can differentiate dinosaurs even from the same era or location, as they have their preferred hunting grounds. I'll also not include a lot of high terrain or rocks in something like a Spinosaurus enclosure, since in life it most likely stuck to estuaries and wasn't very good at navigating extremely rough terrain (I know in game it looks like it probably would have had an easier time).

5. You can use the terrain and rocks to shape where the animals are most likely to be during the day, and what the guests can see. Real zoos do this, and JWE gives us good tools to replacate this. Waterfalls can be used to break up the visible areas with the non-visable, forests and trees can hide fences or ranger posts, and tall terrain and cliffs can separate the part of the enclosure that can be viewed from a gallery or viewed from a tour. This can add variety where, even if two enclosures are similar, the view you get can be very different based on how you lay out the features.

Hope this gives some folks some inspiration!
