You need at least chitin gear so you can tank about 15 hits and if you distract it by leading to the water so it attacks fish while you can tranq it unfortunately you will need a lot of narcotics
P.S: if your on IPad you get an item that boosts taming by 10x use it for spino's
Hey, ok so the center, coordinates 08.1 / 63.4 spinos will spawn there, if is not high enough just kill it, leave the area and come back after 3 mins. Normally works, I found a 150 and I'm taming it rn
stand on a high cliff and shoot it or keep shootong it and running away on a raptor until it's knocked out. it gets distracted very easly by fish, sharks and manta's (even while chasing you) so you may want to shoot it while it's distracted.
