Something logical I think would be that hybrids could socialize with their "parent" species (Stegoceratops with Stegosaurus and Triceratops, Ankylodocus with Diplodocus and Ankylosaurus, Indominus and Spinoraptor with Velocirraptor...and even some T.rex/Indominus, Spinosaurus/Spinoraptor, Indominus/Indoraptor or Indoraptor/Velocirraptor socializing before they try to kill each other)
