Ozzie Sweetwater Posted June 30, 2018 Share Posted June 30, 2018 I have no idea what this is? Any info would be helpful. I found it in a large boulder in the Snowy Mountains in Montana. Thanking you in advance! Link to comment Share on other sites More sharing options...
Miocene_Mason Posted June 30, 2018 Share Posted June 30, 2018 Could be burrows, or could be internal molds of gastropods. Hard to tell. Again, age here is Mississippian. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Ozzie Sweetwater Posted June 30, 2018 Author Share Posted June 30, 2018 Fantastic. It was about 50 yards from the other you assisted in identifying. Any suggestion on where to study up on the Mississipian time period? Link to comment Share on other sites More sharing options...
