Nyctosaurus

This genus of pterosaurs is the only one that does not have claws on its wings. Otherwise, most species looked quite average, similar to the famous Pterodon… until a new, currently unnamed species was discovered in 2003. The species had a huge, antler-like crest, larger than any other pterosaurs crest. Some speculated that there was a flap of tissue in between these antlers, like some other pterosaurs, which could have been used like a sail to enhance its flight. However, research shows that a crest that large would actually impair its flight, so it likely just had an odd set of antlers.
