Re: New BBC series research-fine feathered dinos
While N.A. has had several feathered dinos discovered, it has seemed
that the Mongolian-Chinese fossil record is 'richer' in these animals
(going by the various news outlets.) Is that just chance? Could the
environments have been different enough to spur feathers in what is
It's a matter of preservation.
Think about it: anurognathid pterosaurs, for instance, have so far
_only_ been found in the places with the very best preservation
(Karabastau Fm, ?Tiaojishan Fm, Solnhofen/Eichstätt, Yixian Fm,
Jiufotang Fm). Not one fragment elsewhere so far.
