Pleuromya Posted June 24, 2020 Share Posted June 24, 2020 I'm not sure if this is a nice pattern or perhaps a fossil? Many thanks. Link to comment Share on other sites More sharing options...
Wrangellian Posted June 25, 2020 Share Posted June 25, 2020 It looks like the cross-section of an ammonite.. maybe a few in there. 1 Link to comment Share on other sites More sharing options...

Wrangellian Posted June 25, 2020 Share Posted June 25, 2020 The big wishbone-shaped line is the x-section of an ammonite shell. I think there are smaller x-sections to the left of that showing chamber walls, maybe the inner whorls of the same ammo. The other lines around the piece must be bits of shell too. 1 Link to comment Share on other sites More sharing options...
