Those look *a lot* like concertions to me, especially in the last shot. The top center-ish rock has exactly the kind of concentric striae I'd expect in a concertion.

All of the "pearls" look well polished -- if they were pearls, they've been replaced with something jasper or chalcedony-like.

I'm eager to hear what the pros have to say on this one.
