Simple guide on how to tame,

First, you bring a flying animal, argy recommended in valguero, white cliffs exactly.

Find a nest, or look for deinonychus, they don’t spawn for no reason.

Grab it then run,they WILL chase you, then head back to your base.

Use ac, incubators or AC, hatch it, then raise it. And boom! DEINONYCHUS!

Hope you enjoyed.
