If you accidentally hit one of them and an entire swarm chases after you, the easiest way to deal with it is to use a pteranodon and barrel roll through the swarm. This will deal damage to every dimorphodon in the swarm and if your pteranodon has enough melee damage (700%+) you should be able to one hit kill most of them. Pteranodon also speed up drastically while doing the barrel roll so the dimorphodons canโ€™t really hit it as it yeets past them.
