JonH14 Posted September 23, 2022 Share Posted September 23, 2022 Hey guys, I was in the driftless area fly-fishing, and I found this fossil in a public access creekbed. I'm certain it's fossilized coral, but I was wondering if anyone here knew what kind it was, and if it's of good quality. I'm also curious as to why it looks different than many coral fossils I've seen online (not smooth). Link to comment Share on other sites More sharing options...
FranzBernhard Posted September 23, 2022 Share Posted September 23, 2022 Welcome to TFF from Austria! Not sure, if this is a coral. It could be a weathered chain coral - do you see any structure in those ridges of the first pic? But I am more inclined that this is something geological, something in the line of boxwork weathering.
