Apparently this opinion has been revised.  From Hartmann, S. (2007)
Re-evaluating wing shape in _Archaeopteryx_: Information from the
Thermopolis Specimen. Journal of Vertebrate Plaeontology Vol 27 suppl.
no. 3, pg.87A...


"The Thermopolis Specimen of _Archaeopteryx_ exhibits complete
soft-tissue impressions
near the humerus: the specimen lacks true tertials, as the remiges
decrease rapidly in
size progressing procimally from the elbow.  The series of remiges
terminates less than
half way along the humerus.  The sequential decrease in size and
fur-like feather impressions
evident along this transition are consistent with the preservation of
actual wing morphology,
rather than preservational artefact."
