Finicky question



Sorry to bug everyone over such a detail, but I'm trying to finalize
some illustrations for my web page, and all my dino books are packed
and buried.  No prospect of being able to get to them for some months
yet.  For that matter, I doubt the books I have would offer this
specific bit of information: 

For an illustration of the different shape of squamosal, chasmosaurine
vs. centrosaurine: Where is the lateral anteroventral suture between
the squamosal and whatever it sutures with, in Anchiceratops?  There's
a fenestra (presumably where the ear canal would go through), and a
sort of bony strut below it between the squamosal and the jugal.  Is
the suture at the caudal end of the strut, the rostral end, or in
between?  (I was working from a photo of the panel mount in the
Canadian Museum of Nature, and the rest of the squamosal sutures are
beautifully clear, but that one has me stumped.)

If I can't get any help on this one, I'll just have to fudge it with
some shading, and I'd REALLY prefer not to do that...
