Restore Open DinoWings - Corrected Underside View by Smnt2000 Restore Open DinoWings - Corrected Underside View 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 underside coverts

Dark orange: elongated underside lesser coverts

Light yellow: median underside coverts

Yellow: greater underside coverts

Dark blue: secondaries

Ochre: median primary coverts (lost in modern birds)

Violet: greater underside primary coverts

Red: primaries

'Pink': axillary feathers

Dark green: tertials

Lovely reference! Could you also consider doing the ventral side as well?

Thanks! This is the underside view, so it's also the ventral side ;)

OH! Well, then, I should read the title closer. Sorry! XD

No problem ;)

Great reseource. As detailed in that little reply thread on the other one, it is clearly still very much needed.
