cngodles Posted July 21, 2019 Share Posted July 21, 2019 I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be?

hemipristis Posted July 22, 2019 Share Posted July 22, 2019 This one tickles a memory from my distant past.... Mollusk. Let me dig on this one too 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
cngodles Posted July 22, 2019 Author Share Posted July 22, 2019 From what I'm reading, Carboniferous Oysters are small, so I'll say Mollusk as well. I went though the Index Fossils of North America and tried to find a match, but most things were Triassic to Cretaceous.

Im afraid I don’t have any suggestions on a possible identification for you but the link here will take you to the digital atlas of ancient life which may be helpful.

cngodles Posted July 23, 2019 Author Share Posted July 23, 2019 This might be a Cephalopod as well. A friend of mine suggested Metacoceras or Tainoceras. The ridges could be the nodes.
