Bairdiidae

Anchistrocheles, from here.

Belongs within: Ostracoda.
Contains: Bairdia.

The Bairdiidae are a family of marine ostracods with a convex-backed carapace and wide duplicature. Though they have a long history, extending from the Lower Ordovician to the present, they mostly varied little in morphology throughout this time (Benson et al. 1961).

Characters (from Benson et al. 1961): Carapace convex-backed, mostly with asymmetrical, angulated, convex and concave, round and acuminate "bairdian" shape in lateral view; lateral outlines mostly symmetrically convex and terminally acuminate in dorsal view; left valve larger than right valve, both overreaching and overlapping it; with short, ridge-and-groove hingement and prominent duplicature and vestibule; muscle-scar pattern composed of several discrete spots.
