I found a new place to fossil hunt and it has many more fossils then the normal places I go. Lots and lots of coral, brachiopods, cephalopods, and crystallization. It honestly looks like a coral reef of some kind. I live in middle Tennessee and it's mostly Mississippian and ordovician in my area but there are some areas of Silurian-Devonian. I found this fossil first and thought it was some sort of larger cephalopod, but there were some strange things about it and I started to change my mind. It is a torpedo shaped fossil with crystallization. I will start with the pattern pictures first to show you what I mean and then I will post a picture of the whole thing with a size reference. There are spots distributed around it but they seem to be symmetrical on both "sides," some are clearer than others. There are scalloped edges on the "bottom" of it. There is also an upside down shaped V at the "front-bottom" of it that I think looks kind of like a fish jaw. I do realize that if this is a fish it is very rare for this time period, especially in this sort of shape. If you do believe it is a deteriorated cephalopod, if you could just explain the V shape and the spots, that would help me see it as well. Thanks

Well, without going into a lengthy explanation, yes, I found this in the Arkansas River about 3 feet under the bottom rocks and what we call the NTS (Nasty Toxic ..., unfortunately my rock hound playground is also a delisted superfund site). It took months to finally get it to where it's at now. About half a year in fact of fervent brushing and gentle filing with a diamond coated pen file. Acid has also played a major role but I'm at the point now where I can't risk using more lest I melt what I'm trying to reveal. Is there any readily available household remedy I can use as a protectant of sorts that I could apply on the delicate fossil material so that I can submerge this thing back into acid? Also, would Thyiglycolic acid benefit me here in this scenario? Thanks ~Noah Benzing https://www.youtube.com/watch?v=tn1uSydlkzQ Here is a view of the underside.... I'm getting close to revealing the actual teeth (although I have unfortunately destroyed one or two so far).
