One time my freind and I decided we should move base locations
So we built a raft we threw all of our dino's on it and set sail through the river(witch led into a swamp). We were Noobs and a spino killed us and most of our dinos luckily it ran of and we got our gear back. We only made it out with a trike and a dilo (the trike had most of our stuff luckily). To this day that raft sits in that swamp waiting to be rescued.
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!!!)
