Cyphaspis
''Cyphaspis'' is a genus of small trilobite that lived from the Late Ordovician to the Late Devonian. Fossils have been found in marine strata in what is now Europe, Africa and North America. Various species had a compact body, and a large, bulbous glabellum. Many species had long spines arranged similarly to closely related genera, such as ''Otarian'', ''Otarionella'', ''Chamaeleoaspis'', and ''Namuropyge''. == Sources ==
