These are the Tribes of three leaders but have different ways. Let's take a look!

Rex's Tribe: this is Rex's Tribe as it is powerful and has more people then any other tribe. But they are horrifying to humans even neanderthals too. Plus they eat humans then animals even a human child can be eaten. Only dinosuars are welcome there.

Korokan's Tribe: korokan's tribe is the most peaceful tribe even if you are hurt. They will give you love and comfort as always.

Goratar's Tribe: goratar's tribe is a slave tribe that captures both humans and dinosuars and turn them into slaves. They are evil and greedy. Korokan's Tribe built a wall so that goratar's tribe won't take over. But goratar's and korokan's tribe do not go near Rex's Tribe like Goratar and Korokan said "it's best if we leave them alone." They agreed to build walls around Rex's Tribe so they both won't see the horrors that Rex's Tribe has done.
