Guys all I can say about these guys is DONT TAME THEM BELOW LEVEL 130. Below level 130, their health isn’t that good, they are slow for a fast creature, and their melee is really only good for gathering hide and meat from fish and other useless herbivores. Speaking of fish, at low level megs will tear these guys to shreds during your underwater explorations. However, a level 135-150 wild will make the best non-giga tame to ever walk the ark

To tame a Spino I placed down 3 large bear traps, it easily got stuck and by the time it got out it was torpor running. I easily knocked it out but I must warn you bring A LOT if narcotics mine was only level 4 and it took about 90 narcotics to keep asleep. Didn't take too much meat about 6 percent for every one piece of raw meat. If you are looking to find one on the island map on ARK Survival Evolved there were two spinos near in the southern uplands where there are quite a lot of raptors. Bring bear traps, a bunch of narcotics, and some raw meat if you are looking to tame a Spinosaurus. :)

Don't assume just because they are big, they will be slow. They are insanely fast on land and in sea. Their top speed, reactions, attack speed and turning radius are sharper than their teeth and claws. Just because you are on your prized Raptor, sniping from a distance, does not mean it won't reach you faster than you can turn and start to run away.

Alright I was in front of one with no stuff at the time I was a noob I thought it was a stegosaurus but no it was a big crocodile so I started to punch it but it did not die my point is it is possible but go ham on him at a higher place then he can climb or Rech and go ham on it with all you long range weapons with trank darts or arrows to ok him sorry about typos

As others have already pointed out, the values for raw mutton are off. You need more mutton & narcotics!

I now tamed a 112 Spino on Aberration with 2x taming multiplier. I used mutton only and it ate 30-40 raw mutton (opposed to the 27 calculated). Each piece gave ~3% taming progress, so it finished with ~92% Taming effectiveness. I got 51 bonus levels (calculator said 53).

What you should take away from this: raw prime fish is faster than mutton and as it seems (needs confirmation) produces atleast as many bonus levels as mutton.

I believe Spinos May be bugged right now. Tried to tame two today, both level 280. First one, drew it on to land, knocked it out and put Argie kibble on it and it sank through the ground and out of my reach. I stuck around to see if it might tame anyway and I might be able to recover it. It died due to “drowning” under ground. :(. It took one bite before drowning and got to 1% tame. Second one, pulled it up a hill, knocked it out and put kibble on it as well. Supposedly takes 4 bites of Argie kibble on our sever (15x taming). Each bite gave 1% taming. Fed it a few drugs to keep it asleep and after 4 bites, I stopped drugging it and it woke up. :/
