Sphaerocoryphe

Sphaerocoryphe is a genus of trilobite that lived from the middle Ordovician to the Silurian. Its fossils have been found in Australia, Europe, and North America. Both Sphaerocoryphe and Hemisphaerocoryphe had a characteristically bulbous glabella, and the two may represent only one genus.^[2]
