The skull of Orfnitholestes will be described by Mark Norell (the postcranial
manuscript by me, Cliff Miles, Karen Cloward and John Ostrom is in press). Mark
has had much more preparation done on the skull and did indeed discover that
the so-called base of the horn is a displaced fragment of the right nasal. The
skull is crushed and skewed forcing one side upwards relative to the other.
Mark was generous to let us look at the skull since its preparation and we
fully agree with him.

I read recently that it has been discovered that _Ornitholestes_ did not in
fact possess a horn/ crest/ protuberance on its snout. How accepted is this
view? Does this mean that all the restorations of horned _Ornitholestes_
erroneous? And what about _Proceratosaurus_? Is it still considered a close
relative of _Ornitholestes_, and did it have a horn as well?
(Of course, we can always say that the holotype of _Ornitholestes_ was a
female and thus would not have a horn, while the males would have horns, but
