to escape a spino, go into a dense forest or a area with alots of rocks. While they seem deadly in the waters nor land, they have an abysmal ai when it comes to rocks and alot of tree, and most of the times, they'll get stuck!

Hard to tame i guess. Everytime i shot with my tranq Arrow and when this guy is almost knocked out, he RAN AWAY so fast that i couldn't chase it. Prolly waste of ammo.
