I read recently that it has been discovered that _Ornitholestes_ did not in

view? Does this mean that all the restorations of horned _Ornitholestes_
I think it's discussed in Rauhut's thesis that _O._ did not have a crest,
but I don't know if it is widely accepted.
And what about _Proceratosaurus_? Is it still considered a close relative
of _Ornitholestes_, and did it have a horn as well?
I don't think that _P._ has been considered a close relative for some time
now. Yes, it did still have a crest/horn.
(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,
Actually, we can't just say it. You'd need evidence in the first place that
a specimen did have a crest, then you'd need sufficient number of specimens
in order to demonstrate that there is sexual variation regarding the crest
as well as demonstrating that the different sets of specimens were indeed
the same species and not separate.
