Mummaspis is an extinct genus from a well-known class of fossil marine arthropods, the trilobites, with five known species. It lived during the early part of the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period.
Mummaspis is the genus closest to the common ancestor of Laudonia, the Biceratopsinae and the Bristoliinae. Including the species of Fritzolenellus, this clade is the sister group of Wanneria walcottana and the Holmiidae.
