Inabtanin, and more material of Arambourgiania

[Halichoeres]

This article describes new azhdarchid fossils from Jordan, including both wing elements and jaws from a new genus and species, Inabtanin alarabia, and a humerus from the existing genus Arambourgiania.

Here's the cranial material of Inabtanin.

Probably discussed in the paper, but I wonder how they identified that the jaw elements aren't also from Arambourgiania

I could see the paper, so not paywalled it seems.

If I was asked what Inabtanin is, rather than a pterosaur, I would've guessed it is some sort of chemical compound.

The paper cites the internal structures of the limbs being distinct, with different patterns of hollow elements.

Yeah, as SGD indicates, they have forelimb material from both, and they differ in both size and details of morphology. I just highlighted the head material because I find it easiest to relate to.

Ah, excellent news, thanks!

Yeah, the "-in" ending makes me think of a protein. "Grape dragon" is a fun etymology, though!
