Pleurobema marshalli, the flat pigtoe or Marshall's mussel, is a species of freshwater mussel in the family Unionidae, the river mussels. It is native to Alabama and Mississippi, but it has not been seen since 1980. Though it is still listed as critically endangered on the IUCN Red List[1] and as an endangered species on the US Endangered Species List,[2] it is likely extinct.[3]
