When your taming them I find they like to run away even when they aren’t torpor running. Meaning that if your on say a rock, it’s best to just wait for it for a little bit because it might come running back. They are very sneaky tickle chickens and they will do anything they can to murder you.
Easy to knock it out, harder to tame it. I tamed two theris and mated them, i got twins and i was very happy. Taming it its very hard, in order to knock it out, be at a high rock, then get tranq arrows then knock it out.
If this dino spawns near your base and you are low and mobile player then just do one thing. Put your all stuff in your base and go near the dino then run in opposite side of your base and lead him to far away from your home before he destroy all you have even your pets. just don't uninstall the game bcoz of this😂
