jpc Posted August 6, 2020 Share Posted August 6, 2020 I am always suspicious of so called gastroliths. They could just as well be river cobbles. What makes you think they are gizzardy? Link to comment Share on other sites More sharing options...

No alluvial deposits there. 1 Link to comment Share on other sites More sharing options...
