I present science workshops and one of them focusses on dinosaurs.  We 
have several fossils for people to examine, one of which is a gastrolith 
(stones used by dinosaurs to digest food much like those in a bird 
gizzard).  I am curious to know what characteristics might show that this 
rock was inside of a dinosaur.  What are the clues?
