To "tame" a Deinonychus, you have 2 options.

Option 1. You will need strong creature, and nests. After you will find the nest you have To jumper off your creature, get egg and kill every deino, that will try To attack you. After getting every egg you could find, use Egg Incubator, or 5-7 air conditioners To hatch them (the like 90°C To start hatching).

Option 2. You will need fast creature, like a Pt, wyvern or griffin, and nests. You have To find nests, ten land near one, grab the egg, and run away. Better fly near the ground, over the Cliff, because deinos are stupid, and they will fellow you, no matter what.
