Just to let you know, this is purely a matter of a layman's curiosity.
So yesterday, in the course of conversation my Dad asked me if there
were any omnivorous dinosaurs. I faked some knowledge (Uh, I think
the ostrich mimics? Probably not the Heterodontosaurs?), but wound up
having to say that I didn't know of any specifically, and that on
reflection the whole subject of omnivorous behavior seemed complex
Are there any anatomical features that indicate omnivory (sic - what
would this word be?), and if so, do any dinosaurs have them? Is there
a distinction between omnivores that can eat a variety of foods and
those that have to eat a variety of foods? What distinctions are made
between opportunistic feeding (the grass-eating dogs and chicken-
eating mules of the world) and genuinely omnivorous behavior?
Nothing quite like those simple questions that illuminate one's vast
gulfs of ignorance...
