CamelbackMike Posted July 2, 2021 Share Posted July 2, 2021 Found with the typical ferns found at McAdoo. Is this a seed (or spore) or just some kind of concretion? Link to comment Share on other sites More sharing options...
jikohr Posted July 2, 2021 Share Posted July 2, 2021 I could be wrong but it looks like a bivalve. 1 Link to comment Share on other sites More sharing options...
CamelbackMike Posted July 2, 2021 Author Share Posted July 2, 2021 Certainly a possibility. I guess I just never thought bivalves would be in the same levels as the ferns. Link to comment Share on other sites More sharing options...
hemipristis Posted July 3, 2021 Share Posted July 3, 2021 Seed pod, I believe. Ive only seen flattened impressions before from that area, and yours is 3D.

CamelbackMike Posted July 3, 2021 Author Share Posted July 3, 2021 Tim, Thank you. I did not realize that those early seed trees were around then. I am glad I posted - several in the past I have thrown away because the people I have showed them to had no idea. Mike 1 Link to comment Share on other sites More sharing options...
