When Sordes was discovered in 1971, paleontologists found tiny, dense hairs on the body imprinted in the rock. This supported the theory that pterosaurs probably did have a layer of down fur. The hair found on the Sordes skeleton served as insulation and provided a streamlined flight profile. But scientists were confused at why pterosaur fossils found in Germany, having the best preserved fossils, yielded no fur.
Sordes had a 0.45 m (1.5 feet) wingspan. It had a slender, not round, head with long, pointed jaws. Its teeth were small and slanted. It had a thick and compacted neck. It had a long tail, accounting for over half its length. Unlike most pterosaurs, it had no head crest. Sordes had wing membranes attached to the legs and a membrane between the legs.
