Here we have a piece of matrix LOADED with of marine fossils. A layer of rock containing numerous fossils from different creatures is often called a hash plate. Can you see the white nuggets? Locals referred to those as "white gold." The reason is, when out fossil hunting in this area, the presence white nuggets means the rock is filled with fossil treasures. This one tiny little sample contains numerous fish teeth/bones, shells and best of all...coprolites. These bits and bobs accumulated in shallow waters near the shore of the Western Interior Seaway that covered the great plains of North America 95 million years ago.
This hash plate of marine fossils was found and sent to me by Ramo Decker.
