As for a lake dwelling animal Caudipteryx would certainly have been a fish
eater.  The teeth seem suited for this purpose.  But what about snails?
While the teeth are unsuited for this, they could have been scooped up,
swallowed whole, and then processed by gastroliths (get yer protein and
calcium in one shot).  Also it seems possible that Caudipteryx might also
have been omnivorous, eating water plants and such.  Why else would this
animal have gastroliths?
