The best way of using the Dimorphodons is, without a joke, to leave them at home. Increase their Health and Melee Damage and they will be the perfect guards for your house/base. As soon as someone try to break in your house the Dimorphodons will start to attack the burglar/intruder. Just be sure u have more than one Dimorphodon at home! One Dimorphodon is easily killed but a hole swarm is a real Curse for every Intruder. But of course you can take Dimorphodons with u outside. They will sit on your shoulder and as soon as someone/something attacks you, they will attack and protect you.
