Just fly over to the redwood biom. Search for a pack with a decent level and lure it up the mountain. Soon they will glitch into the rocks and you can tame them even with a bow. They can't catch you or flee.
THE best way to tame anything is to use an argy cage, simply use like 5 dinosaur gateways made of stone and keep one gate door open before you find a dino to tame, once you do, lead it to the cage and then run out through one of the gaps between the gateway frames and obviously close the door and, tadaa, one stuck dino to tame
