If you want to tame a spino here are the steps I took to taming it

1Find it's territory:spino's have a territory to themselves this can help you observe it from a distance

2Get on a cliff or high place the spino can't reach you and shoot it(carry ALOT of tranqs if your gonna try tame this)

3They are extremely fast so when they start running you might wanna try snipping it from a distance as closing the distance will be extremely difficult

4Make sure you have enough narcotics and meat to tame it

Bonus tip:if you want you can use narcotic tripwire traps or dinosaurs like pachy or basilisk to speed up knocking it out

The best thing to find one is flying over the river randomly. if you found one make sure he cant hit you (go on a boulder or on a cliff) and shoot at him with tranq arrows. If he is unconsious just put prime or normal meat in him and make sure you have enough narcotic (i tamed a level 50 first and it needed about 200) and if you are escorting him into your base do NOT attack any strong dinos he cant handle it if its a level 100 or less spino that does not mean its weak but you have to level him a bit before killing strong dinos (the spino level 50 got 22 level with the taming bonus and he died at escorting him to my base from a therizino btw that was 30 mins ago now im mad at this game, it was my first spino)

On mobile, when I was new and low level but wanted to tame spinos - I used to bring in some life bait to the spinos to distract it from attacking me (tamed carbos and parasaurs with high health, around 800 or 1200) or let it aggro a wild Dino for a bit, and when it focuses on the Dino bait, I hop to a safe distance and tranq it until it was knocked out. It took me at least 10-30 tranq arrows.

I just give it raw fish, and when taming it took too much time and the torpor bar starts draining fast I give it some narcotics or bio toxin I get from killing nearby cnidarias (at least 60 narcotics or 30+ bio toxins) then just wait.

Kept doing it until I have like 4 spinos run after runs.

The spinos often spawn on the coasts and beaches in the footpaw region which is where I usually found them. Sometimes they do spawn in the river near the volcano and the waterfall and rivers in the redwood forest.

How to tame a Spinosaurus easily:-

S1: To find a Spinosaurus, go to rivers (mainly the rivers near the Redwoods).

S2: Options:-

1 Clear out the area if you think anything could trouble you while taming it and if you have a quick mount, knock it out that way.

2 Or build atleast pillars which are 12-14 times higher and knock it out that way.

3 If both of them are risky, build 15-20 fence foundations and stone walls of atleast 3-4 times high and finally finish it with ramps and knock it out with that way.

S3: Knock it out with either tranquilizer darts and a long rifle or tranq arrows and a crossbow.

S4: Feed it Argentavis Kibble (Old ARK Mobile only), Exceptional Kibble, Raw prime fish meat or Raw fish meat.

S5: You have a Spinosaurus :D

Facts:-

F1: It's saddle unlocks on lvl 71.

F2: It is quite quick in water as well as land.

F3: It also has an untameable version in Extinction which is Corrupted Spinosaurus.

F4: When in water, it has a Hydrated buff which increases it's damage and resistance.
