COMPARISON
Gorjunopora n. gen. differs from Filites Počta in Barrande, 1894 in presence of long superior and internal hemisepta as well as in alternating nodes on low keel. Gorjunopora n. gen. differs from Penniretepora d’Orbigny, 1849 in the shape of autozooecial chambers (triangular to trapezoid vs rectangular to pentagonal in Penniretepora ), presence of long superior and internal hemisepta as well as in alternating nodes on low keel
