Search Met@hub for the article named “Jurassic World Alive: Spawn Mechanics Post 1.3 update…”
Para and Allo are both Local 4 dinos and if you are in that zone, you will get a lot of them (check the spawn rate %). Global spawns also appear frequently in all the local zones along with zone dinosaur.
One local zone dinosaur do appear in other zones, but that occurrence is very rare. So, best bet is to go to that local zone where the chances increase tremendously based on the dino rarity. Zones are usually small covering only a couple of miles. Cross zone walking would be difficult, but covering on bike/car should be easy.
Note each of the zones around your area and the spawn time of dinos. That has helped me get the dinos I want much easier!
