Condylopyge[1] is a genus of agnostid trilobite that lived during the late Lower and early Middle Cambrian, in what are today Canada (Newfoundland and New Brunswick), the Czech Republic, England and Wales, France, Germany, Italy, Morocco, the Russian Federation (North-East Siberia), Spain, Turkey and Sweden.
Condylopyge is long ranging, possibly spanning the early Cambrian Terreneuvian Series in Nuneaton, central England into at least Drumian strata (middle stage of the Miaolingian Series) at various locations elsewhere.
The characteristic lateral expansion of the frontal glabellar lobe, occipital structures, and pygidial axis with three pairs of lateral lobes and a terminal piece differentiate Condylopygidae from all other agnostids.
The presence of a spine on the occipital band has been recognised as a distinctive feature of condylopygoids (Rushton 1966: p. 29).
The pygidium may carry a pair of backwardly directed spines, but this also occurs regularly in Pleuroctenium.
