I've tamed many spinos all from the same trap, 4 stone dino gates and one large bear trap. Place three down so you can make a rectanlge out of the four, then put the large bear trap down inside of them. Shoot the spino, and run through the trap. Go to the other side and place the dino gate to finish the rectangle. Now you just need lots of narcotic arrows and lots of narcotics( boi toxin works best). I tamed 10 spinos on mobile with this method, one being level 200. But the trap works great for other gaming devices to.
