Monopleura Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Hippuritoida Family: Monopleuridae Genus: Monopleura[1] Monopleura is a genus of bivalves. Their fossils have been dated back to the Cretaceous Period (145.5 million to 65.5 million years ago), and they are members of strange clams known as the pachyodonts. The thick triangular shell in this genus is capped by a smaller dome-shaped shell. Some of the pachyodonts possessed open passageways through the shell that allowed for fluids to pass. The pachyodont bivalves were habitually sedentary and grew upright with the pointed end anchored in substrate. [2]
