I laugh when I read about people freaking out over dimorphodons on mobile because they accidentally stepped on one and have 25+ of them come after them. I have stepped on these buggers so many times I lost count. However there is a way to live if you do step on one and a swarm comes for you. All you need to do is have a large such as a therizinosaurs,bronto,rex,giga,etc. Stay in one place preferably on a rock or such where you have higher ground. Then just start attacking them continuously without moving from that spot. You will begin to see their bodies shoot off like baseballs. This is the fun lovable sport called dimorph ball.
When in areas that have many dimorphadon remember to be careful and not to hit one by accident when fighting other creatures as you can easily be overwhelmed.your mount will not be able to save you as they deal damage directly to the rider.
I went to raid a base with 4 buddies, a rex, 3 carnos, and a bronto with a platform saddle and cannons. All we heard was a whistle and i swear about 50 of these little devil's swarmed the whole group, killing everyone in the group and one carno, the turrets shredded everything else, but the rex must have ran off and we never got a death message so its still out there in the jungle.
