_Cosesaurus aviceps_ is a prolacertid - probably a juvenile
_Macrocnemus_. As such it's no more related to the dinosaurs than

I vaguely recall reading somewhere that the original slab bearing the
first _Compsognathus_ specimen may have been "polished" in the
process of preparing the skeleton for public view. At the time, no
one expected _Compsognathus_ to be feathered, so no one would have
bothered looking for them. Any feather impressions may have been
inadvertently rubbed off.
I must confess that I don't actually believe a word of this.
