edteach Posted December 27, 2019 Share Posted December 27, 2019 I was at a creek bed today looking for stone points and artifacts. I found these two fossils Any help IDing them appreciated. Link to comment Share on other sites More sharing options...
Rockwood Posted December 27, 2019 Share Posted December 27, 2019 Sorry. I think the first one is a form of banded chert. The other looks more mineral than fossil in nature to me as well. Link to comment Share on other sites More sharing options...
edteach Posted December 27, 2019 Author Share Posted December 27, 2019 The second photo is defiantly a fossil. Looks to be some kind of plant maybe or coral Link to comment Share on other sites More sharing options...
edteach Posted December 27, 2019 Author Share Posted December 27, 2019 Some better photos of the fossil. Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted December 28, 2019 Share Posted December 28, 2019 I'm thinking the first one may a clam shell fragment. The second one does look a bit like a coral but I would like to see better photos of it from the same angle as the last one in the first series of photos. Mark.

edteach Posted December 28, 2019 Author Share Posted December 28, 2019 I can get my light box out and Digital SLR if these are not good enough. The one I don't think it a bivalve its almost like a piece of a tree bark. Link to comment Share on other sites More sharing options...

edteach Posted December 28, 2019 Author Share Posted December 28, 2019 If you are talking about the chirt flake in the rock that looks like some kind of fossil then yes its I believe a chert flake. But that is not why I picked it up its the stippling pattern in the other rock. The second rock has more curves IMO than a bivalve. Link to comment Share on other sites More sharing options...

edteach Posted December 28, 2019 Author Share Posted December 28, 2019 Must be something strange or I would have gotten its a this or that. The one that is a fossil for sure seems to me to be more rounded than a bivalve. Also the indention of the lines are too deep IMHO also. I have tried to look at other Bivalve fossils from this area on line. It could be a type of bivalve fossil. I can not match the pattern though. I sent pictures into a few fossil groups for ID. Maybe they can confirm what it is. Link to comment Share on other sites More sharing options...
edteach Posted December 28, 2019 Author Share Posted December 28, 2019 Going through my other fossil finds from the same area and I found one that somewhat matches, could this be a large rugose coral fossil 1 Link to comment Share on other sites More sharing options...

I can't find a good match in my collection though. Link to comment Share on other sites More sharing options...
edteach Posted December 28, 2019 Author Share Posted December 28, 2019 I found one that matches close but its a small piece. This goes under the surrounding material more but I don't want to destroy it by trying to remove it. Link to comment Share on other sites More sharing options...
Scylla Posted December 28, 2019 Share Posted December 28, 2019 If this is carboniferous in age maybe an inflated calamites? If it is in chert and from a predominately marine environment, maybe exterior of a horn coral. Those are my best guesses but I can't wait to find out what it really is. The second one stumps me.

Rockwood Posted December 28, 2019 Share Posted December 28, 2019 Do those ridges look as if they were little cubes that were fused into a row when you look at it in hand ? It would indicate rugose coral. Link to comment Share on other sites More sharing options...

I was thinking rugose coral, as well. The second one reminds me of a styolite. Steve Link to comment Share on other sites More sharing options...

Peto Lithos Posted December 28, 2019 Share Posted December 28, 2019 The second one appears to be weathering due to water. Link to comment Share on other sites More sharing options...

I can't argue with it, but the features so exposed do look to be the result of pressure dissolution earlier in diagenesis to me. Link to comment Share on other sites More sharing options...
ToeKnee Posted December 28, 2019 Share Posted December 28, 2019 I just came across some rugosa yesterday in the Decorah that resembles that pattern in the chert. I haven't positively ID'd these yet, but Lambeophyllum or Streptelasma maybe. Link to comment Share on other sites More sharing options...

I am in no way an expert of any sort, but this sure looks like the rugose coral fossils that I find in the Missouri Ozarks. Link to comment Share on other sites More sharing options...
