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