minnbuckeye Posted August 22 Share Posted August 22 I had a left over 5 pound piece of matrix sitting outside from last summer's trip to the Burlington, Iowa area. Finally this summer, I broke up the Mississippian age rock a bit, soaked it in acid for a few weeks, and then extracted these teeth from the softened matrix. 20 Link to post Share on other sites

Joseph Fossil Posted August 23 Share Posted August 23 @minnbuckeye These fossil shark teeth are truly awesome! Nice Job!! I've heard there are still some exposed Burlington Keokuk fish layer road cuts still exposed in parts of Western Illinois!!! I think close to the Mississippi River but not 100% sure!!! Any suggestions (without giving too much information away publicly) on where I could find them? Link to post Share on other sites
