Without wanting to refudiate Scott Hartman, I concur. But I'd be
quite happy to be convinced that the absence is real. Because the
humerus of _Archaeopteryx_ is quite long compared to the birds that
came after it, this would translate into a sizeable gap.

I know that coverts have been reported for _Microraptor_, but I wasn't
aware that anyone had found definitive humeral feathers
Also, unless something has changed recently, AFAIK it is not known
if_Confuciusornis_ had humeral feathers. In many specimens the
primaries and certain rectrices are clearly defined, but the degree of
preservation is poor for most of the other feathers.
