Anisopyge is an extinct genus of trilobite belonging to the order Proetida and family Phillipsiidae.[2] Specimens have been found in Permian beds in North and Central America.[3][4]
The genus was among the last surviving trilobite groups. It may have evolved from Sevillea, diversifying to fill empty ecological niches.[4]
