screel0118 Posted November 28, 2021 Share Posted November 28, 2021 Found this in Alabama mountains near Huntsville. Was in a washed out area of rock. Found others too. Any ideas? 1 Link to comment Share on other sites More sharing options...

I think that has to be fragments of the colony. You must be right about this. 1 Link to comment Share on other sites More sharing options...
Jeffrey P Posted November 28, 2021 Share Posted November 28, 2021 I agree about Archimedes, but very interesting preservation. I believe they are prevalent in the Mississippian rocks around Huntsville. 2 Link to comment Share on other sites More sharing options...

FossilNerd Posted November 28, 2021 Share Posted November 28, 2021 I’m in the Archimedes camp as well. Typical preservation is mainly of the central axial column with the fragile fronds being broken off. Your specimen seems to have the fronds (at least partially) intact. I have collected dozens of Archimedes and only found a few with the preservation seen here. So, while it is not a horseshoe crab, I still think it’s a neat and uncommon find. A decent article from the KGS (Kentucky Geological Survey) can be found here with published paper references cited at the bottom should you be so inclined to learn more about them. https://www.uky.edu/KGS/fossils/fossil-month-09-2018-Archimedes.php 3 1 The good thing about science is that it's true whether or not you believe in it. -Neil deGrasse Tyson Everyone you will ever meet knows something you don't. -Bill Nye (The Science Guy) Link to comment Share on other sites More sharing options...
