Which makes it so that the cohabitation preferences of various species in the game don't make any sense. They should've adopted a system like Planet Zoo where interspecies enrichment/cohabitation preferences are based on animals that a particular species would actually coexist with in the wild. For example, all the herbivores of the Hell Creek and Lance Formations should be comfortable being housed together. Same holds true for herbivores of the Morrison and related formations. The system they have now is so generic and illogical it boggles the mind. Carnivore, pterosaur, and marine creature cohabitation preferences are even more illogical when you really examine them. Point is, for your suggestions to work, the entire interspecies cohabitation system needs a complete or near-complete overhaul to reflect my statements above. Otherwise, it does not nor ever will work the way it should.
Speaking of quality of life improvements, the dinosaur cohabitation element needs work also.
In the short run, I would like to see improvements on the pachycephalosaurs cohabitation:
1) Given that Homalocephale is incapable of combat, it should have the same cohabitation preferences as Dryosaurus, Struthiomimus, Archaeornithomimus, Gallimimus, and hadrosaurs.
2) Pachycephalosaurs of all types can mutually cohabit with ornithomimids and hadrosaurs.
3) As stegosaurs dislike ankylosaurs and ceratopsians, stegosaurs can only tolerate Homalocephale but not the fighting pachycephalosaurs especially Dracorex, Stygimoloch, Stegoceras (if added), and Pachycephalosaurus. It would be better if the Jurassic herbivores and the Late Cretaceous herbivores fight for territory.
4) By trading the fighting pachycpehalosaurs' like relationship with stegosaurs, pachycephalosaurs and ceratopsians can mutually cohabit.
I would appreciate if the other amendments are made:
1) Majungasaurus cannot cohabit with Qianzhousaurus
2) Albertosaurus cannot cohabit with Carnotaurus
3) Metriacanthosaurus cannot cohabit with Allosaurus
4) Pentaceratops cannot cohabit with Styracosaurus, Pachyrhinosaurus, and Triceratops.
5) Pentaceratops like Alamosaurus
6) Nasutoceratops cannot cohabit with Styracosaurus
7) Torosaurus can cohabit with Triceratops
8) Camarasaurus can cohabit with Apatosaurus
9) Diplodocus can mutually cohabit with Camarasaurus, Apatosaurus, and Brachiosaurus
10) Pteranodon like Geosternbergia
