Hole in map cedrus forest

There a hole in the Riparia where you can fall in as dino almost every size. Once I falled in and my friend tried to get me out as rex - he fell too. Unless you have a friend or yoh're a flier, you can't get out without loosing growth. I think there's shouldn't be such a place where you stuck and just can't get out back

I fell in the pit during the fight and couldn't get out of it

There's no pit
