RE: Cloudy With A Chance Of New Papers
David, I am thinking he'd assume *Tianyulong* does nothing to change his
opinion: The long quill-like structures are just that -- long and quill-like --
while everything else is degraded collagen, which is what Lingham-Soliar's last
two papers on the subject went through a lot of hoops to show. Moreover, even
if the pterosaurian "pycnofibres" are homologous, one could not produce an
argument that all dinosaurs should have similar hair-like fibres of a
homologous origin assumed in each ancestor, and therefore that they'd be
present in any taxon such as all of those assumed (like *Sinosauropteryx* to
have degraded collagen frills or such.
