Ceratobairdia is an extinct genus of ostracod (seed shrimp) belonging to the order Podocopida and family Bairdiidae.[1] Specimens have been found in Permian[2] to Jurassic[3] beds in North America,[2] China,[4] and Europe.[3]
The genus is heavily ornamented,[5] and a distinctive characteristic is that its valves (shells) have a flat ventral surface and a ventrolateral alate ridge (a winglike ridge extending from the ventral surface to the side of the valve.)[6] The genus is also notable as a Lazarus taxon, disappearing in the Permian-Triassic extinction event and reappearing in the Carnian,[5] an interval of at least 15 million years.
