First build 4 or 10 stone gates and place 3 or 9. Take a Dino that can tank some attacks from the spino and put it in your trap. If it’s in, launge the last gate. Walk out the trap with your dino(if your dino is bigger than the gate this won’t work). Now what I would recommend is leave him alone for a game day. When you’ll come back he is hungry and will eat faster. I also recommend taking a smoothing balm(mobile) the spino likes meat and argentavis kibble. It’s torpor goes down fast so take some biotonic with you. The saddle is on lvl 71. Once it’s tamed. 🔥🔥🔥🔥. It will be the fastest and the strongest Dino you’ll have. Spino>ark(except wild giga)
