    We got these out of a trunk upopened since 1939.
    I seem to remember that dinosaurs would eat rocks much like chickens to help grind and digest food and they would get polished and rounded.
    Any paleontologist out there?

      You found them in a dinosaur unopened since 1939? ;-))

      The irregular one looks like a calcite concretion.

      They even could be pearls of non nacreous shells too!

      What are the mesurements, I'm sure some specialists will be helpful :-)
