I would reccomend using bear traps for theese and if you dont have metal use bolas too bring both if affordable, bring some meat, and craft a saddle, the way i tamed was with my pteranodon, i was flying above an island where i saw 2 and i set up 4 bear traps on the floor in case of a pack and lured them to the traps i chose one, shot him down with narcotic arrows in a crossbow, the other ones i shot with my pistol and then gave the unconcious one some meat and did not need narcotics, i am now planning to find a pachy and ankylo and explore the island even more, overall, raptors are speedy, strong and very mobile, they can jump high and everything, a great start dino, would recommend getting one!
