after reading some the comments below. just for a little imput. dragons are mythical yes, but as a bird keeper and insect breeder, ive noticed that most animals capible of flight have a wingspand about duble the length of their body. meaning that each wing spread out is the total length of the body, from nostril to the tip of the tail. i dont know if this helps but i always keep it in mind when drawing my dragons to keep things sort of looking right

Hi! ^^
I'm doing a project (check my latest journal) about dragons and how to learn to draw them. I've been recently investigating a lot about the skeleton and musculature for the realism of the posibility of flight of a dragon, and a debate about the wing's scapula's position would be great, since most think that they belong to the same shoulder, or scapula, and I theorized that it would make impossible the flight. So, I know there are two scapula, the problem is where?

Have you ever read "The Flight of Dragons" by Peter Dickinson? It has a lot of interesting information about how dragons COULD exist if they did. He says that nature has never allowed any animal (insects don't count) to have more than four limbs, so a dragon with four scapulas wouldn't exist, technically.
If it DID, though, I always figured behind the arms, but much bigger to allow for more muscles and flight power.


I totally agree whit the muscles part. Not only like, biceps and all that stuff. Pectorals are very important for flight I think...(at least I tried to explain why would it be like that and it worked), so I theorized their pectorals and back muscles would be divided (slightly, not so marked) for either the wing or the arm. Another theory commonly known is that they can't move well their arms while flying and vice-verse. Although I very much disagree with total dysfunction, it may be that when in flight or run, the division of the muscle is then made... that it isn't absolute, and connects with the two limbs at the same time.
If a dragon with four scapulas doesn't exist, then maybe it's a second shoulder coming from the same scapula, just that a little bit apart.
I will try and search for that book. It would be a lot of fun reading.

I think in order to work like wings, they would have to work almost completely independently from the arms -- including the scapula. In Peter Dickinson's book he described dragons' wings as being more like "modified ribs".
Look at the musculature of birds and bats -- birds have that large specially-shaped sternum that has the primary flight muscles attached to it. I just don't know the muscle names anymore.
Yes, do read the book! I found it a very stimulating, thought-provoking read.

Two different shaped scapula would , and does make sense. However technically they would no longer be the typical dragon, as in many stories dragons attack with or use their arms whilst in flight. Perhaps if you made a dragon's legs coming from the front of the body, and their wings a third down thier body, then maybe that would work. But yeah, I'm no expert on animal anatomy and arrangement
