Vanuxemia waynesvillensis n. sp. is the only known species of Vanuxemia from the Upper Ordovician of the classical Cincinnati region. The abruptly flattened anterior margin and the nearly terminal beaks of this species show great similarity to those of a closely related family of monomyarian pelecypods, the Ambonychiidae. This convergence in shell form indicates a similar adaptation to the same mode of life, both being endobyssate or epibyssate suspension feeders.
