Re: Feather Flap
I agree completely. The problem is trying to frame an
ecomorphological model for climbing in theropods that can be "tested".
Something along the lines of biomechanical studies combined with
modern analogs - such as what was done with the study of _Mononykus_'s
forelimbs in a fairly recent study.
True, it is difficult. One approach is essentially a biomechanical
process of elimination. If we first quantify forelimb loadings, and
then look at the range of possible sources for that loading regime, I
suspect that only a couple of causes will be viable, given other
One set of characters of note in the regard are actually structural
characters: extant arboreal birds (including modern passerines and
falconimorphs, for example) seem to fall within a similar range for
certain quantitative, structural characters associated with limb
That sounds very interesting. Do you have a particular study in mind?
The statement was based upon work I am in the middle of as we speak
(ie. unpublished data). It will make its debut at SVP if my abstract
is accepted. If not, then at some future date.
