Cluster of Orthotetes Brachiopod Fossils

Fossil plate was found in the Edwardsville Formation of Floyd County, Indiana, USA. The fossils date to the lower Carboniferous (Mississippian) Period. The brachiopods on the plate appear to be Orthotetes keokuk. It is somewhat rare to find so many clustered together.

Thanks to Kenny for the image.

Unidentified Pyritized Ammonite Fossils

My favorite place to buy fossils in Lyme Regis, England was not really a dedicated fossil seller at all. The small out of the way shop was called Connie's Curios & Fossils which was next to the post office. I had visited 3 larger more prominent fossil stores and my main focus was finding fossils from the area. While the other shops had nicer more expensive fossils this store had small bags of mostly fossils in the rough from the area. Once I got back to the United States I started using a dental pick and engraver to remove matrix to show more of the ammonite fossils. I was also able to get the pyrite to shine more.
