If you find a pack of raptors wait till one of them wanders away or the others die,but make sure it isnt the alpha raotor because you cant tame those.(still be carful because i saw a lone one but it wasn't alone)Then you bola the raptor knock it out with you fists club,of tranq arrows.(traq arrows recomended because it can still attack you)Then feed it some meat,get it a saddle if your high enuogh level and you'll have a great buddy.
