I built a small wooden house boat specifically to go down the river between fars peak and smugglers pass. I was half way between the mouth of the river and the bottom of that frozen peak where there where rocks in the stream, when I saw a spino. At the time I was pretty low level, so I waited for it to fight some dinos and get lower in health. Well, it happened. A herd of trikes fought it, and when I thought it was dead, I started passing through. Then a raptor pack showed, so I stood in the center of my boat, and attacked their heads through my walls. When I finally killed the pack, the spino was back. It wasn't dead enough for me to kill it at the time, so I had 10 seconds to process what to do: save my chest of stuff, or get out. Well I had to destroy my wall to escape. To most, that is crazy to try to escape such a fast dino, but to me, it wasn't. I had always put points to my own movement speed since the very beginning. I out ran that sucker. So dont ever assume their dead. Never.
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 I saw a high level spino wandering around and killing everything in sight and when I shot my bow it ran away and I was like what the hell? Killing them isn’t hard just tame a few Dilophosaurs and let them spit poison at the Spino before killing it with your pistols. If you don’t have pistols, get more and higher leveled Dilo and stand back and shoot it with a bow to assist.
