Wings and Wishbones Two

#wings #aviananatomy #wingbones

let us consider the evolution of birds from Theropods

The Theropod has hardly any sternum and lacks a pronounced furcula or wishbone.

The Archaeopteryx has a furcula but no "Keel" however they were thought to be more gliders than fliers.

Finally a chicken. A distinctive furcula and a "keel" !

Note that they also lack scapulas shoulder bones.

The wing muscles attach to the sternum and wishbone.

Note how and where the muscles attach.

Consider this where would the wing muscles attach on a winged humanoid "biped" or quadroped  with six limbs? If you don't want to give them a pronounced "keel" or sternum do the flight muscles attach to the furcula instead? Or do you redesign the clavicle and scapula bones? 

No do not moan but its my fantasy and go back to drawing wings like they're pasted onto the back .

Next time more anatomy to study and please think about!

It took me half a hour to find a collection of images to share so why havn't you done that too?

I will be looking at the body stance of bird species that walk and climb or run so much as they fly.

WINGS AND WISHBONES ONE

#anatomy #birds #wings #furcula #wishbone #illustration

This is a closeup of an illustration in an old Time-Life Science book in my personal collection about #birds . It shows the the bottom of the wing joint the keel bone and the wishbone or Furcula of a bird.

Many illustrators and artists when drawing winged bipeds disregard avian anatomy and when asked about it use its my style or fantasy or the clients fantasy as an excuse.

Now i'm not saying you should draw angels with a massive keel bone but if you're drawing some kind of winged biped hybrid or alien thats avian or modelled on an avian please please please just stop drawing wings like they're stuck onto the back. 

Yes birds have large pectorals attached to their keel bone but they do have muscles around that wing joint ! This diagram averages things out but over the next few posts I'll be showing you some reference images I've compiled. Meanwhile until the next post study these two images.

and yes I will be discussing the biped with wings issue ! 

ONE GIMP PATTERN transformed into ...

Sooo #Gimp comes with several Patterns and what what happens if you edit one ?

I filled a Background layer with the Leopard Skin Pattern

How to hide the tiling and make the s;potted pattern different and more interesting.

For a change I started with INVERT and then other filters

Three simple changes !

This month on my #patreon I am doing 5 rewards

Reward 3 is about to be uploaded. There will be a mixture of technozi and background texture files.

This was reward two in the April series .

Cherry blossoms Elsewhere

While searching for rarer less often seen Cherry Blossom viewing images I found this reminder that lovers of cherry blossom can be found in many nations and eras.

Playing with Lava

#lava #gimp #filters

Here's some results from playing with the Lava Filter in Gimp and using different gradients and then adding a few more edits.

A Blue Gradient with some Sharpen and a few other tweaks

Maxxing the darks and adding texture !

Use the Color tools to strengthen /greens and Blues !

Hope this gives you some ideas for texture experiments ! 

Tell me which one you like the most and I'll put it on my #deviantart
