Condylopygoidea
The Condylopygidae Raymond (2013) RAYMOND, P. E., 1913: Some changes in the names of genera of trilobites. ''The Ottawa Naturalist'', 26: 137−142. are a family of small trilobites that lived during the Middle Cambrian, and found in Canada (Newfoundland and Nova Scotia), the Czech Republic, Germany, France, Spain, England, Wales, Sweden, and the Russian Federation (Siberia). They uniquely differ from all other Agnostina in having the frontal glabellar lobe wider than the rear lobe. The Condylopygidae are the only family assigned to the Condylopygoidea superfamily. Taxonomy The Condylopygoidea are an isolated branch in the Agnostina suborder that occur approximately contemporaneously with the Peronopsidae, the earliest representatives of the main branch of the Agnostina. One species, ''Peronopsis palmadon'', appears intermediate between Peronopsidae and Condylopygidae, but it is not clear whether ''P. palmadon'' is ancestral to the Condylopygidae - a regression towards ancest ...
