re: Boreopterus snout holes
If anyone is interested, my take on Boreopterus can be found at:
Note that in the original illustration
The rostrum is drawn as traditional, that is, pristine â?? without holes
anterior to the antorbital fenestra.
Using Photoshop, from half a world away, and without an airplane ticket or
hotel bill, I was able to provide a smidge more detail. Thank you, Mike Hanson,
for confirming that you also saw the holes in the snout. That validates the use
of photography and the computer to establish details. Now, remember: _how_ we
interpret those holes, and everything else about the skull, has nothing to do
At this point we can look at the ceiling and wonder what those holes are. Then
we can look at other taxa to see if such holes are 'absent' or 'present'.
If I can find similar holes bounded by the nasal (in pink) and the jugal (in
blue) in other taxa preceding this one and trace the character back to its
origins, then I have a case. Conveniently, you can follow the evidence at
various places within www.pterosaurinfo.com. It's all in there.
On the other hand, if _anyone_ can find a pristine rostrum without similar
holes bounded by the nasal and jugal _anywhere_ within the ornithocheiridae,
cycnorhamphidae or any taxa following Scaphognathus, then you will have made
your case. Of course, there could be identical bone rot in every specimen from
every strata... but, that would be your evidence to present. You're also going
to have to show that the nasal and jugal do not continue beyond the antorbital
I look forward to seeing the evidence. And this _is_ science at its best.
Only a _real_ pseudoscientist would use words in lieu of evidence.
As always, my 'cards' are on the table. Where are yours?
PS. And thank you, Jaime, for seconding the hypothesis of a separate naris in
the Pterodactylus sp. AMNH 1942.
