Paleozoic mollusk: Hyolithes

January 1, 1964

An unusually well-preserved Ordovician fossil from Czechoslovakia shows that the enigmatic paired structures once thought to be outgrowths of the operculum of Hyolithes are really independent structures lying between the operculumn and the aperture of the shell. The find seems to provide conclusive proof of the morphologic uniqueness of hyolithids.
