Hi everyone this is how I tamed the spino in singleplayer ( I am level 80 something)

What you need:

your gonna need a Diplodocus and a Diplodocus saddle and pump the Diplodocus into HEALTH so it doesent die. Also get a Longneck rifle and tranq darts. (Optional) Use dododex and select the spinos level and see the amount of tranq darts it will take to knock out. Also bring like 90 narcotics or more OR a lot of bio toxin ( dododex will give details about how much it will need, and put its level in before checking )

Instructions

Now set your diplo to Neutral and get in passenger seat in front of spino, command it to attack spino or aggro it ( stay in one of the back passenger seats so the diplo keeps aggroing the spino before it hits you ) and start using tranquilizers darts on it. once the spino starts running dismount and chase and shoot it until it falls asleep ( dismount because diplos are slow ) and bring prime meat or kibble or use( raw fish or raw meat if you bring more bio toxin or narcotics since they tame slower and decrease effectiveness ) and wait for tame

IMPORTANT: DO NOT LET ANY AGGRESSIVE DINOS ATTACK THE SPINO OR GET NEAR IT, IT CAN RUIN EFFECTIVNESS.

If your still reading you can stop now thats all i have. Heres a story. A ichthyornis ruined my spinos effectiveness and I sacraficed it the end.
