ynot Posted June 16, 2019 Share Posted June 16, 2019 Most of these look like steinkerns (internal cast) of the shells. As such it is hard to make a species ID. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Wrangellian Posted June 17, 2019 Share Posted June 17, 2019 OK, maybe someone can narrow down the formation and the IDs based on that. All I can say at this point is it looks Cenozoic in age... 1 Link to comment Share on other sites More sharing options...

Plax Posted May 24, 2022 Share Posted May 24, 2022 I'd say those steinkerns could be identified to genus. Link to comment Share on other sites More sharing options...
