This is very late, since the book is almost out
a year or so at the moment, but yesterday my parents came back from London and
bought me a copy. After reading some segments in the book, a couple of questions
and comments began to grow in my head and I wonder if any one could help me with
them...
- In the chapter about Hesperosaurus, which is
on overall pretty good, but it seems that Kenneth Carpenter and al. have
a problem with skulls. They can't
seem to get the elements right, especially in the out-line drawings with the
bone
identification. For instance, on
the photograph on page 60 there are 10 skull bones known (excluding the lower
jaw)
and the drawings based on the skull
elements on the next page show only 9 bones. And that is not all, in the
top
drawing the middle supraorbital is
missing, while in the bottom drawing the partial braincase is missing.
- Again in the Hesperosaurus chapter, the
different skull elements (when available of course on page 61:) can hardly
be
matched: the nasal is drawn with a
slight bend, which is not there in the actual material), the maxilla is far more
slender than it is drawn on page 61
and so fort. In total the upper drawing has only one bone correct and that is
the
quadrate.
Has anyone else noticed this or am I just on my
own here? Currently work has started on a new skull reconstruction of
Hesperosaurus (based on the photograph) , I'll inform the list when it's
done.
- The Hesperosaurus-chapter is getting a beating
here, but again, if we look at page 62 (does this make me sound like
Jim's dad from American Pie...?
;)), there is this skull reconstruction of Stegosaurus stenops. This skull looks
to
strange IMHO and is more like an
intermediate in a morph-program from the skull of Hesperosaurus to the real
skull
of Stegosaurus stenops. It is based
on the skull/ skull-elements of DMNH 33365, but does the skull of this
specimen really look like this? I
don't know who has acces to the actual material, but if someone is possible to
do so,
any comments would be
welcome.
The Phylogenetic Analyis of the Ankylosauria was
one of the chapters I was most anticipating too, but a couple of genera emerged
that are unknown to me. Could anyone help me with some information or pictures
about the following genera?
- Polacanthus rudgwickensis
- Nodocephalosaurus kirtlandensis
- Pinacosaurus mephistocephalus
- Animantarx ramaljonesi
- Stegopelta landerensis
- Texasetes pleurohalio
Thanks in advance for any help,
Peace,
Rutger Jansma
