Re: GSP's hadrosaurian reconstructions


    Just a clarification of what I was questioning.   I was NOT saying "How
dare he put these silly-looking huge necks on the hadrosaurs" - I was asking
2 distinct questions (although I was imprecise in asking them) -

    1)     What precisely were the silhouettes of the hadrosaur necks
supposed to represent - a flap of skin (as some artists have put on the back
of _Parasaurolophus_'s head and neck), OR a 'withers'-type neck (as
mentioned in Sam Girouard's post)?

    2)    What were these ideas based on?

    I have had answers to both these questions: 1) a 'withers' type neck and
2) based on fossilized skin impressions (including nuchal ligaments).

    I still say that SOME of the reconstructions look silly to me - remember
I grew up starting in the 1950's, so I've seen several variants of
reconstructions throughout the years.  Also, remember that I'm from Phila.,
where I have had close contact with _Hadrosaurus folkii_ and _Corythosaurus_
at ANSP since 1985 (and actually since 1958 in their original mounts).
Naturally, I think that I know what a hadrosaur ought to look like.  :-)

    Looking over the reconstructions in the publication, I LIKE the thick
neck with _Shantungosaurus_, _Saurolophus_, _Anatotitan_, _Kritosaurus_, and
_Edmontosaurus_.  I DON'T LIKE the neck with _Ouranosaurus_,
_Tsintaosaurus_, _Corythosaurus_, and _Parasaurolophus_.

    Essentially, I find that the longer-necked morphs don't look as good as
the shorter-necked morphs - AT LEAST TO MY ADMITTEDLY PREJUDICED EYES.

    It is quite likely, as Peter pointed out in his post (below), that not
ALL of the hadrosaurians had the same exact neck - even if Greg decided to
draw them that way (True, Peter was talking about iguanas, but...).

   As I said in my original post -  I LIKE A LOT OF GREG'S WORK!!!  I just
had a few nits to pick with these particular reconstructions.

    (By the way, way back in 1985-1986, I didn't like the nearly
chicken-like drawing of _T. rex_ that Greg had created for the ANSP [on a
blackboard, originally].  I still have some specific problems with that
picture, but the avian nature of the _T. rex_ is no longer a problem to me -
and hasn't been for some time).
