For taming, since they run away super fast, a good trap is a 3x4 stone foundation with door frames that are 3 high (they can walk over 2 tall) with a ramp leading up. U might need some extra supper pillars for the ramp at the bottom depending on the land u use tho. Make sure its semi close to the water or the spino will lose interest. Then u can just lure it in, its pretty wide so it should he easy, then u basically just shoot it until its down. Ez tame. Dont forget to brung narcotics tho.
