The way I tamed one: place a stone pillar, then on that one another then on that one another until you have a ten tall pillar thing, then one stone ceiling on the very top pillar. around that stone ceiling make a 3x3 stone ceiling thingy. I have one near the red woods for Rex's around that area. When a rex near tower camp thing ,tranq(when fleas, you must have good aim)if successful it will get knocked out obviouslyπŸ€“ Then just feed (Bring cryopod as usual)
