Hi Friends,  Offered for sale is a Large Bellerophon Gastropod Rare Fossil From Kansas City USA 200 Grams. This stone came from deep in the limestone layers and was naturally compressed or flattened into the limestone; there is a resulting crack on the small curve of the shell, or impression as it may be because it has been filled with minerals. This is an unusually large specimen of a rare type extinct gastropod (sea snail) which the shell resembles a nautilus shape. This specimen came from Upper Pennsylvanian Paleolithic limestone dated around 290-300 million years ago. Long ago there was a shallow sea in the Kansas City area which was on the west edge of the Pangaea continent. This stone is a surviving remnant of that era. This is a genuine extremely ancient fossil hard to find giant specimen.
