Re: R: Giant carnivorous geese

<I don't know of any living carnivorous animals that utilize 
gastroliths, but it wouldn't surprise me if some did.  Any slight 
advantage posed by gastroliths would have made evolving the behavior 
of using them attractive in dinosaurs (and other animals), and 
certainly there might be use for them in carnivores, especially 
in theropod dinosaurs, which likely possessed a gizard anyway.>

The implicit question is whether use of gastroliths could develop 
in a carnivore or might it be an indication that the animal was 
a herbivore that became an omnivore or carnivore?
No axe, or stone, to grind, but I'm wondering if use of gastroliths 
has anything to say about ancestry.
