Re: Struthiomimus Exhibit
No joint is apparent
distinguishing the distal ends of the radius and ulna from the metacarpals,
nor is there (at least as viewed in the web page) any sign of a pteroid
or of a propatagium.
I disagree; if you look at the first photograph, towards the more proximal
part of the wing, there's a rectangular shadow across a section of the
patagium. It looks like the humerus is bent back into the plane of the
photograph, then the radius/ulna is bent forward towards us (and is
contained in the shadow), and the metacarpals are bent up at an angle from
And the elbow points back across and inside the bronze area of thw wing, so
the propatagium is shown. You can see a slightly folded area (it looks a
little crumpled on first glance) proximal from the wrist joint, which is
presumably the leading edge of the propatagium. It looks like the
propatagium is folded in accordance with the elbow joint, and presumably the
pteroid would be the thing making it look more like a fold than a crumple.
one sees things resembling a
structural members (they do not look like simple buckling of the wing
membrane), as if the artist were trying to pattern the pterosaur wings
those of a bat (albeit incorrectly even for a bat).
Hmmm, i think the sculpter was trying to show actinofibrils in the wing, and
those bigger more heavily defined ones that i guess you're referring too are
just buckling patterns in the wing that've been *guided* by the fibres. The
fourth digit seems to be bent up along a different plane from the
metacarpals, so this would fold the corresponding section of wing upwards as
well, and the structural member is just a fibre that happens to accentuate
the folding at that point. Ditto for the folded bit further down, at the
edge of the shadowed section of wing. Anyway, thats what it looks like to
Agree that it's a pretty neat peice of work regardless.
