Wow, another special image similar to a posting 2 days ago. The Mississippian Period brachiopod fossil
Productus wortheni found
in the Knobstone Formation of Clark County, Indiana, USA shown in image. The special item about this image is the spines preserved in the sandstone matrix. They are so delicate yet survived the fossilization process and here they are hundreds of millions a years later.
Kenny, thanks for the image of this very sweet find.
