Megalodon is an extinct genus of bivalve Molluscs that reportedly lived from the Devonian to the Jurassic Period.[1] It is not clear, however, that all the fossils assigned to Megalodon from that span of time really belong in the same genus.[2] Jurassic relatives of Megalodon such as Pachyrisma grande were closely related to the rudists.[3]
