Description
Anhanguera at sunset.

The appearance of the "beak" in my art is quite speculative. I wanted to do something different from the other illustrations I saw of anhanguerid, and it may seem that I made a "soft skin" or "scaly" on the "beak", but that wasn't my intention! I didn't want to represent scales in the "beak"! I wanted the beak to have a less smooth and glossy appearance, which makes it look like there are scales or a carunculated skin over the beak and that wasn't exactly my intention. In the case of my Anhanguera, I wanted to make the beak with a keratinous, rigid and hardened structure, but with a cracked aspect, which can cause the appearance that there is a soft and scaly tissue covering the beak, but it wasn't a scaly tissue I wanted to do it here.

Talking a little bit about pterosaur beaks, according to Mark Witton, in the book "Pterosaurs": "The integument of pterosaur heads is also known in some detail. Many pterosaurs, even those that bore teeth, had hard, keratinous extensions of both jaw tips that we could consider “beaks”. Exquisitely preserved fossils of toothless pterosaurs show that these rhamphothecae extend over much of the jaw, which agrees with observations that pterosaur jaw bones, like those of birds, often have deep blood vessel channels impressed into their surface by the existence of a tough, horny covering. Similar blood vessel imprints are also found on bony pterosaur crests, suggesting these may also have been covered in a similar horny material".
