If you are having a hard time finding spino's in their respective spawn zones (especially Ragnarok), kill all the fish in that area. They share the same spawn capacity and can be out spawned by coles! ( up vote so Rag players know!!!)
Once tried to tame one for my bf while he was offline bc he wanted one. Flew with my Pterra and shot it full of 20!!!!! tranq arrows . Didn’t even flinch. I got too cocky and went too close to the edge of the cliff i was standing on. I fell off RIGHT IN FRONT OF THE SPINO. it’s health was low enough that it started to run away. Without looking back, i whistled for my Pterra to follow and ran for my life. currently trying to get another one :( wish me luck!
If you’re low level, stay really far away from dis fish eating rex, it spawns in rivers and around lakes, by water. It’ll try kill you if you come anywhere near it. In my opinion, best way to get rid of it is to lead it to a herd of sauropods or dangerous herbivores. If there is none nearby, run away from any water source and it will sometimes just lose interest
As far as I know, only 3 wild carnivores will aggro onto the sight of your spino, other Spinos, Rexes, and Gigas. You can probably outfight other spinos, outrun rexes, or outfight lower level ones, and outrun gigas. Very useful.
I found one across from my base. I followed one of the tamimg pen tutorials but made the pen to small and the game kept crashing. I died over 5 times and finally got it trapped then a raptor killed me, when I respawned I saw the spino running towards my base. I thought it was the end of my dinos but no, it looked at my dodo the wrong way and all my creatures (10 dodo, 1 dimorphodon, two dilos,1 Iguanadon, one petradon, and two parasaurs) all mobbed it and it started running faster than anything I've seen in ark. I ended up making a huge pen and having to chase the spino into it because of the trauma from all those dodos... Now I have it, but am over level 52 and don't have a saddle for it.
If being chased don’t think going into the water or scaling a cliff is a good idea, they’re great swimmers and when on four legs and climb decently. They are distracted easily, so try to get it to agro on a herd of trikes or other herbivores and run off to a safe distance.
