Restore Open DinoWings - Final Corrections by Smnt2000 Restore Open DinoWings - Final Corrections by Smnt2000

It seems to me that I have never hidden the fact that I am not perfect.  I know, I’m almost there. But alas, it can happen to make some mistakes.
Among the most popular articles and diagrams I’ve written, my post on how to portrait the wings of the members of Aviremigia have had a great success (first part : ktboundary-smnt2000.blogspot.i…; second part: ktboundary-smnt2000.blogspot.i…; third part: ktboundary-smnt2000.blogspot.i…). This is understandable: the wings of birds are among the most difficult animal parts to draw accurately, since they require an adequate understanding of their structure and variety, and this problem is also reflected in artistic depictions of extinct species, which may have feathered limbs more or less similar to those of their relatives today. This common problem pushed me to do a quick and simple guide on how to illustrate them. Despite the good will, the discoveries made in recent years and the anatomical oversights dictated by the lack of experience (J. Campbell- Smith, of all people, is the one who inspired me to revise everything, and for that I thank her very much) required a considerable restoration work that took me more a lot of time, but I hope that the results are satisfactory.

Models: Archaeopteryx and a generic maniraptoriform (based on Anchiornis)

Orange: lesser coverts

Dark orange: elongated lesser coverts

Light blue: median coverts

Blue: greater coverts

Dark blue: secondaries

Light brown: median primary coverts (lost in modern birds)

Brown: greater primary coverts

Red: primaries

Green: scapulars (speculative)

Dark green: tertials (speculative)

Alula not present, but you can add it on the first digit.

Is there any chance of the wing feathers being... Shorter?
Smnt2000 Featured By Owner May 19, 2014  Hobbyist Traditional Artist
I don't understand, why the wing featheres should be shorter?
MaxterandKiwiKing Featured By Owner May 19, 2014  Hobbyist Digital Artist
No real reason. I just wonder if the wing size could differ from species to species.
Smnt2000 Featured By Owner May 20, 2014  Hobbyist Traditional Artist
That is certainly plausible. For example, Microraptor has very long primary remiges, which give to its wings an almost swallow-like silhouette.
However it seems that in a lot of maniraptorans the wing feathers' lenght is similar to the humerus lenght. That is clear in some excellent fossils (Caudipteryx, Anchiornis, Jinfengopteryx, Similicaudipteryx, etc.) and seems to be the norm in many moden birds too, from ostriches to common pigeons (or, to put in another way, all the species with a 'generic' type of wing).

Nevertheless maybe one of the best tutorials about this topic at the moment.

Thank you very much :)

My friend, Scapulars and even more Tertials are veeeery speculative.
A fairer guess would've been Alula (or how I call them in non-avians: "Pseudoalula" - made-up term!), shown from the Microraptor fossil.
The multi-layering of Coverts is well-made!
Another thing to nitpick: According to skeletal reconstructions by Hartman, Headden, etc. the claw would rather point forward in a topview. That's obviously perspective-wise, but as you show it it looks more like the fingers are pointing backwards.
