This is an interesting trilobite from the Lower Ordovician in France, identified as Colpocoryphe deani. It is suspected that the species Colpocoryphe deani could be a homonym and/or synonym. This species is in conflict with Gravicalymene deani Ingham, 1977, which means that the younger taxon violates the ICZN. It is assumed that Colpocoryphe deani is the younger taxon. Traditionally, many Colpocoryphe finds from the Arenig in France are determined as Colpocoryphe thorali Dean, 1966. Therefore, it is likely that the author who proposed Colpocoryphe deani as a new taxon wanted to dedicate this species to Dean. Although Colpocoryphe deani is frequently used, no reference to the author of the species can be found. |
