Menaspiformes are an extinct order of holocephalans known from the Carboniferous and Permian periods,^[1] with a possible member, Listracanthus,^[2] known from the Early Triassic. Members of the order are believed to be durophagous benthic carnivores.^[1]^[3] While historically menaspiforms were classified under Chimaeriformes,^[2] they are today recognized as a separate order.^[3]
