Wyvern Musculature by KatePfeilschiefter Wyvern Musculature by KatePfeilschiefter
Some quickish muscle drawings, as people have been requesting wyvern anatomy and I myself have to figure out what wyverns in Aerie will look like. They'll have to exist alongside the larger hexapods without competing for the same niche. And will most likely be less intelligent and more colonial than their six-limbed cousins. A good comparison between the wyverns and the hexapods in Aerie would be that between wolves and coyotes. Farmers don't like either of them, but one is smaller, more troublesome, and much more numerous.

There are multiple ways to structure a wyvern. Whether they're bird, bat or pterosaur based.
Both of these are very bird like, with keeled sternums, coracoids and furcula.

The first wyvern walks like a bat or a pterosaur would, and can gallop quite quickly when using its wings as forearms. It's thoracic vertebrae is only partially fused, leaving the spine semi- flexible. I imagine this guy as gliding and climbing a lot. This dragon is what an early wyvern could look like when transitioning from a hexapod to a four limbed biped, depending on the phylogeny.

The bottom wyvern is essentially a modified heron, with a birds skeleton. This guy is smaller and can take off much more quickly. He's a bit more like a medieval wyvern with a snakish neck and tail, and a short bulbous midsection.

It's wonderfull picture and very impresive scientific research abiut dragons' evolution! I'm working about it too -…

maybe you would like it and even help me with this hard problem?

Of course, keep in mind though that as this is a mythical creature this isn't the end all be all of references for a wyvern. Just a few of my own ideas on how to create them.

Is this available as an open reference? It would be a great tutorial.

I really like the detail of these pieces. I'm writing a story that is inclusive of wyverns and feel this does them justice. Also, the wings functioning as forelimbs and the structure of the half-paw that would allow it to be weight bearing is quite original.

This is gorgeous work! It reminds me of the dragon musculature Todd Lockwood made on his website.
