The best thing to find one is flying over the river randomly. if you found one make sure he cant hit you (go on a boulder or on a cliff) and shoot at him with tranq arrows. If he is unconsious just put prime or normal meat in him and make sure you have enough narcotic (i tamed a level 50 first and it needed about 200) and if you are escorting him into your base do NOT attack any strong dinos he cant handle it if its a level 100 or less spino that does not mean its weak but you have to level him a bit before killing strong dinos (the spino level 50 got 22 level with the taming bonus and he died at escorting him to my base from a therizino btw that was 30 mins ago now im mad at this game, it was my first spino)
