Pterorhynchus wellnhoferi by Archosaurian Pterorhynchus wellnhoferi by Archosaurian
Before there was Darwinopterus there was the sadly ignored yet completely amazing Pterorhynchus.

What evidence is there for the tail flanges, and how wide-spread are they in pterosaurs?

There are some photos of the type specimen having undergone preparation, the tail vanes run all along the tail. Only Pterorhynchus<i/>, Rhamphorhynchus, and Sordes have been preserved so as to show tail vane remains. In Sordes the vane seems to be a long, thin segmented paddle shape.

So really, we have no idea what structure most pterosaurs had on their tails. The leaf-shaped vane ala Rhamphorhynchus might be unique to that genus?

Awesome work as usual!

How strange-looking with the serrated tail flanges...pretty cool, nevertheless!

Wasn't it found that it had a nasoanteorbital frenetra, instead of the two openings seperated?

I think there was only ever one reconstruction of it with a full nasoantorbital fenestra, and I'm pretty sure it was the result of a misinterpretation due to the dorsoventral crushing of the right side of the skull displacing a lachrymal. The naris is still quite visible in the photos and the x-rays.
