They are small animals that can fit neatly in the palm of your hand. There are two species, namely Kuehneosaurus latus and Kuehneosuchus latissimus. One has wide wings, while the other has shorter wings, made of a layer of stretched skin above its elongated ribs, which allows them to fly from tree to tree.

Besides Kuehneosaurus latus and Kuehneosuchus latissimus, they noted the existence of reptiles with complex teeth, the trilophosaur Variodens, and the aquatic Pachystropheus that likely lived like modern otters, probably consuming shrimp and small fish. These creatures fell or their bones were swept into caves and cracks in limestone.
