If you wanna tame the Spinosaurus, use these following steps:

DIFFICULTY- [6/10]

THINGS YOU'LL NEED:

1. A Crossbow and some tranq arrows (or) A Long Neck Rifle and tranquilizer darts.

2. 15-20 fence foundations (stone), 15-20 stone walls and 6 ramps (If you want to trap and tame)

3. Exceptional Kibble (or) Argentavis Kibble [Old ARK Mobile only], Raw prime fish meat (or) Raw fish meat.

TAMING:

METHOD NO. 1:

Clear out the area if you think anything could trouble you while taming it and if you have a quick mount (such as Gallimimus, Raptor etc), knock it out that way.

DIFFICULTY FOR METHOD 1- 9/10 [COMPLICATED CAUSE YOU'LL HAVE TO RUN AROUND WHEN THE TORPOR WILL INCREASE].

METHOD NO. 2;

If you have a tanky mount (such as Brontosaurus, Paraceratherium etc) it will ressist the damage while you're knocking it.

DIFFICULTY FOR METHOD 2- 6/10 [INTERMEDIATE CAUSE THE DINO WILL RESSIST THE DAMAGE WHILE KNOCKING IT OUT.]

METHOD NO. 3:

Build 10-12 stone pillars high and knock it out while it'll bite your pillars and it can't even reach you, but don't use pillars less than 10.

DIFFICULTY FOR METHOD 3-8/10 [ARDUOUS CAUSE WHEN THE TORPOR'S HIGH YOU'LL HAVE TO RUN AROUND].

METHOD NO. 4:

Build 15-20 stone fence foundations and stone walls of atleast 3-4 times higher and finally, the ramps, then lure the Spinosaurus into the the trap and knock it out.

DIFFICULTY FOR METHOD 4- 1/10 [EFFORTLESS CAUSE IT WON'T WANDER AROUND AND YOU DON'T HAVE TO RUN AROUND].

You have a Spinosaurus. Congratulations :D
