UPDATE: What I thought were basal tail vertebrae are in fact dorsal vertebrae, as denoted in the original description. The confusion was resolved with a higher quality photo I recently found.

Introducing the mind-bogglingly bizarre new pterosaur from the Swiss Alps! Behold Raeticodactylus filisurensis! Prepare to be boggled!

Note: There is some suspicion it might belong to Caviramus, an equally weird pterosaur genus known only from bits of lower jaw, but what an odd little jaw it is! After looking at both taxa it seems that the two are generically distinct, but they likely are very close relatives, belonging to the same unnamed clade of ultra-weird basal pterosaurs.

I'm also a bit uncomfortable about how the legs are positioned, the legs in this thing appear to have been completely erect as opposed to outward-facing in other pterosaurs so it may not have had the range of motion necessary to spread the legs out in flight as in other pterosaurs. Still, it likely had a uropatagium since there is a fragmentary specimen of a pterosaur with a similarly structured leg that preserves impressions of one.
