These beauts are an extinct fossilized button coral, Gymnophyllum wardi. The article mentioned that they are from the Pennsylvanian part of the Carboniferous period. I found these along the shoreline of Okmulgee lake in Okmulgee, Oklahoma. Apparently G. wardi is the only species found in the genus Gymnophyllum and may only be exclusively found at Okmulgee Lake or neighboring Dripping Springs lake although I'm not positive on that. The ones below are about 10 to 15 mm. One thing that I found interesting is that the waves from the lake constantly expose more of these fossils over time perhaps bring more in from the lake bottom. They are very lightweight. I recall not finding these along a section of shoreline where another person had been collecting them only to come back the next day and finding several in the same area! That is pretty exciting! Comments welcome as always.
