Crystalized Welks (W2)
Notes specific to this specimen: Fossil welks are much rarer than the clams found at Rucks Pit and most of them have no crystals. But, when you do find a nice crystal-line specimen, there’s nothing like it in the world! This is a single welk with a natural opening on its dorsal (top) allowing you to see the crystal lining of the shell and the gray sparite “floor” that was the sediment which partially filled the shell after the animal had died. Very unusual.
