Leperditiidae

Left lateral view of Paramoelleritia wangchengyuani, from Wang & Lundin (2004).

Belongs within: Ostracoda.

The Leperditiidae are a group of large ostracods (sometimes up to 8 cm in length) with thickly calcified shells known from the Ordovician to the Devonian. They are particularly well represented in the fossil record as moults from multiple instars may potentially be preserved (Benson et al. 1961).

Characters (from Benson et al. 1961): Large, thick-walled; cardinal angles well defined; greatest height medial to posterior; dorsal margin straight, valves strongly unequal, surface smooth to slightly ornamented; adductor muscle scar large, composed of numerous secondary scars; anterodorsal eye tubercle usually present.
