Restore Folded DinoWings - Corrections by Smnt2000 Restore Folded DinoWings - 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.

Would this one or this:…

apply to Velociraptor and other dromaeosaurs?
Smnt2000 Featured By Owner Apr 20, 2014  Hobbyist Traditional Artist
In both the descriptions they say that this is the correct one, so yeah, it would apply on dromaeosaurids too.

So their wings were this big? The more you know...
Smnt2000 Featured By Owner Apr 20, 2014  Hobbyist Traditional Artist
Big arms=big wings. Small arms=small wings. It's as simple as that.

Thanks anyway.

Happy to hear you say that :)

Now, this will come in handy. I always have such trouble visualizing exactly how the feathers overlap on a folded arm/wing. :)

Glad to hear that this will be usefull :)
