Is Kepodactylus a Germanodactylid?

Kepodactylus insperatus (Harris and Carpenter 1996, DMNH 21684) was described as a large pterodactyloid. Only a few pieces are known (Fig. 1, left). The humerus (here scaled to half the published scale bar) most closely resembles that of Germanodactylus cristatus.


Figure 1. Kepodactylus (left) compared to Germanodactylus cristatus (greyed out, right). The humerus is a close match. The cervical is larger. What Harris and Carpenter (1996) described as a possible distal wing phalanx is much too large. I’m wondering if it is a distal radius?

Kepodactylus gives us not much to go on, but the best match I was able to find is with Germanodactylus cristatus. If so, this continues the matches seen in Late Jurassic Solnhofen pterosaur fauna now starting to add up in Late Jurassic North America. Perhaps from such as Kepodactylus we would eventually get Eopteranodon, Pteranodon and Nyctosaurus.

As always, I encourage readers to see specimens, make observations and come to your own conclusions. Test. Test. And test again.

Evidence and support in the form of nexus, pdf and jpeg files will be sent to all who request additional data.
