Jurassic; The Allosaurus in 'Jurassic World: Fallen Kingdom' has a plain smooth back but in the game 'Jurassic World Evolution' and its sequel, it has little spikes in its back and in 'Jurassic World: Dominion' the Allosaurus is fully grown, so he is much bigger and has spikes. this could mean that in Fallen Kingdom he was still a juvenile and in JWE 1 and 2, he is becoming an adult, and in Dominion he is now fully grown
