DaredChance Posted April 15, 2021 Share Posted April 15, 2021 Found this while at work so unfortunately this was the only picture I could snap since rock was too large to carry back at the time. This is the first time I've seen this pattern and shape in a fossil around here so I'm hoping someone knows what it is. It's length was roughly 3-5 inches if thats of any help.

GeschWhat Posted April 15, 2021 Share Posted April 15, 2021 Very interesting! Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
ClearLake Posted April 15, 2021 Share Posted April 15, 2021 Welcome to the forum! That is indeed an interesting find. I wish I had an answer for you at the moment but I can’t place that pattern right now even though I think I have seen it before. Do you know the age of the rocks? And the brachiopod to the left is interesting as well. Link to comment Share on other sites More sharing options...
deutscheben Posted April 15, 2021 Share Posted April 15, 2021 That looks like the plant Calamites, a horsetail relative- from that and the brachiopod I would guess this is Pennsylvanian in age. Link to comment Share on other sites More sharing options...
Rockwood Posted April 15, 2021 Share Posted April 15, 2021 I think this is a strange presentation of a rugose coral. 3 Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 15, 2021 Share Posted April 15, 2021 I agree with Rugose coral and brachiopod.

Jackson g Posted April 15, 2021 Share Posted April 15, 2021 Ditto for IDs being internal molds of a productid brach and a rugose coral. More than likely its weathered Burlington Formation chert. Link to comment Share on other sites More sharing options...
JimB88 Posted April 15, 2021 Share Posted April 15, 2021 Yes, its most likely amplexus, a very long rugose coral. 4 Link to comment Share on other sites More sharing options...

I've learned something new for the day, I guess I can goof off the rest of the day! Thanks Link to comment Share on other sites More sharing options...
ParkerPaleo Posted April 15, 2021 Share Posted April 15, 2021 I don't know the pattern but most of the rocks near Springfield are the Burlington Limestone, Mississippian age. Link to comment Share on other sites More sharing options...
