Asaphus expansus (/ˈæsæfʌs ɛkspænsʌs/) is the type species of the asaphid trilobite genus Asaphus. It was previously classified as Entomostracites expansus before being split off into its own genus. [2]
Most specimens have been obtained in Northern Europe, with one known exeption being in North America. [3]
Asaphus expansus differs from related species in its genus by having a cranidium that is considered broad, as opposed to its more medium sized counterparts. Examples of these other species are A. fallax and A. raniceps. [4]
