polyphyodonty in dinosaurs

["Ken Kinman" <kinman@hotmail.com>]

    As an on-topic spin on the former discussion, I would assume that 
dinosaurs, most other reptiles, and non-amniotes, all are polyphyodont 
(multiple-to-continuous tooth replacements) and also homodont (all teeth 
generally of similar shape, usually more conical than flat).  Therefore the 
wisdom-tooth problem would occur rarely, if ever, in something like 
dinosaurs (or any other non-mammal).
    An on-topic and interesting question would be whether plant-eating 
dinosaurs ever develop heterodont teeth with mammal-like "molars" for 
grinding.  If they do, I assume they do not develop the same precise kind of 
occlusion, since dinosaur identification is rarely, if ever, based on dental 
characteristics (or am I wrong on that?).
