Ogygopsis

OGYGOPSIS The exoskeleton of this genus is broadly oval and gently convex, with the axis tapering along its whole length. The near rectangular glabella extends close to the head margin, with moderate-size eyes in a central position, and triangular cheeks. The thorax is made up of eight segments, with deep furrows in the pleurae. For a Cambrian trilobite the tail shield is exceptionally large - its length actually exceeds that of the head shield. The pleural fields in the tail are strongly furrowed. Habitat: Ogygopsis lived on the bottom of shelf seas.
