I saw one of these in the woods while I was a little way off collecting stones. They weren't any bolas on me so I ride to the house, take some and raw prime meat, get on my ptranodon and fly to the area. The Tapj disappeared and I accidentally ran out of stamina and landed.

I landed on totanomirma's nest and compy puck. Lost me petranodon.

Moral of the story: take an arg, not a ptranodon. The search can take a long time and even safe places can be dangers. Those things disappear fast, really fast, so I'd u should lose I sight u batter give up.
