Some ceratopsian heads

I'm liking the Anchiceratops. All of these heads have been drawn based on their sculls and the Anchi didn't have it's lower jaw in the picture (as most ceratopsian pics I use) so I think it could be undersized :/ I dunno!
These were done on separate papers and I combined them with PhotoShop so don't mind the background.

I draw my dinos based on their skulls and/or skeletons! And I have limited supply of good material with me in the hospital. *sigh*


I'm TRYING to draw anatomically correct dinosaurs while in the hospital but I tend to fail in most of them :/ I have limited knowledge of dinosaurs muscles and their attachment and effect on the appearance of their fleshed body.

If some of the great paleoartists here on DeviantArt sees these, please understand X( I wish I had more knowledge of this stuff, but living in this country gives me limited resources on really good dinosaur books.

Links to some seriously detailed paleolife websites will be appreciated! I want to get news about the new dino findings other paleodeviant here seem to get all the time. Some of you are even paleontologist (makes me jealous).

Edit: And I know they don't have those horns in their cheeks! For some reason I added them while drawing... Don't ask why. It just happened :/
