The tests were run on fleshed-out models, with all the rugosities restored.

Not that I remember reading in the Earth article.  I remember mention
was made of human and cat FOVs, though.  The dino taxa tested, as far
as I can remember, were: Tyrannosaurus, Nanotyrannus, and
Carcharodontosaurus.  There may have been a few more, but I can't
remember which.  Maybe Mickey can fill us in as I don't have the
article handy...
