The Dimornal which resembles a Dimorphodon, is the small flying reptile that has developed a symbiotic relation ship with the  Brachaclipse Lizard and the Eclipse Tree. Every Eclipse Tree has a hole somewhere, that hole becomes the Dimornal's home and someday it's own grave. They live in packs, eat the fresh growing fruits and parasites on the Brachaclipse. They also fertilize the tree. The Eclipse Tree is naturally somewhat hollow, having tunnels on the inside allows the Dimornal colony to grow. Along with giving a place to live and to leave their dead. Never get too close to them, they have sickle like claws and sharp teeth. Not to forget also a ankylosaurs like clubbed tail, which is sturdier in females than males. Males have larger crests than females, as a safety measure they have strong but amazingly light weight shells that they will retreat into if they are threatened.
