Re: A "new" theory on Oviraptor philoceratops (I think)



Tooth is incorrect and I knew that.

Headden's point makes sense, animals which have specialised feeding habits,
(even if they only make use of them occasionally) can and do develope
specialised adaptations. But this is my question:

Would it really take such a strong jaw to break open what must have been
(barring a special adaptation to let air in using other ways then through
the shell wall) relatively large and fragile eggs, why not use a forarm or a
rock?

Even in tropical environments seasones have their effects and most animals
tend to appear to have been using simultaneuos mass breeding seasones to
overwhelm predators (Hypsilophodontids, Hadrosaurs, Protoceratopsids,
probably Sauropods). It should also be considered that nests would have been
relatively well defended, there is a difference betwean a small bird vs. a
snake that is quite capable of eating it and a small Theropod vs. the
falling hoofs of a large Hadrosaur.

Does anyone have any idea what defended hypsilophodonted nest sites? I am
thinking of the nests found in North America (mountain runner, I forget the
latin name), I know troodontind eggs were found at the same site and have
always wondered how they got along.

Anyway Deer have been documented eating birds caught in banding nets, its
always good to remember that!
