theropod "hornlets"

[lundq@uky.campus.mci.net (J. Lundquist)]

My observation as a complete amateur on "hornlets" in theropods:

They would make wonderful protection for the eyes during bringing down prey.

Also a question:  judging from book illustrations, there is a considerable
difference in how the "hornlets" are depicted.  Especially in older books
the horns look more like simple ridges; newer illustrations seem to show a
much more distinct horn--higher, pointier.  Is this just artistic license?
