Beyrichiacea

Male (above) and female Kloedenia normalis, from Benson et al. (1961).


Belongs within: Ostracoda.
Contains: Beyrichia.

The Beyrichiacea are a group of ostracods known from the late Ordovician to the early Permian (Whatley et al. 1993) characterised by the dimorphic development of a ventral to anteroventral lobe or pouch.

Characters (from Benson et al. 1961): Straight-hinged ostracodes with subequal ends or forward swing, mostly with well-developed lobes and sulci and showing tendency to have carinal, velate, and marginal structures; dimorphism usually well defined.
