Ceratobairdia is an extinct genus of ostracod (seed shrimp) belonging to the order Podocopida and family Bairdiidae.{{cite journal |first1=G. |last1=Becker |first2=S.Q. |last2=Wang |year=1992 |title=Kirkbyacea and Bairdiacea (Ostracoda) from the Palaeozoic of China |journal=Palaeontographica Abteilung A |volume=224 |number=1–54}} Specimens have been found in Permian to Jurassic beds in North America, China, and Europe.
The genus is heavily ornamented, 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.){{cite journal |last1=Forel |first1=Marie-Béatrice |last2=Ozsvárt |first2=Péter |last3=Moix |first3=Patrice |title=Carnian (Late Triassic) ostracods from the Sorgun Ophiolitic Mélange (Southern Turkey): Taxonomy, palaeoenvironment, and evidence of predation |journal=Palaeontologia Electronica |date=2018 |volume=21 |issue=2 |doi=10.26879/852|doi-access=free |hdl=10831/67481 |hdl-access=free }} The genus is also notable as a Lazarus taxon, disappearing in the Permian-Triassic extinction event and reappearing in the Carnian,{{cite journal |last1=Forel |first1=M.-B. |last2=Crasquin |first2=S. |title=Bounded by crises: An overview of the evolution of marine ostracods during the Triassic |journal=Marine Micropaleontology |date=October 2020 |volume=174 |pages=101925 |doi=10.1016/j.marmicro.2020.101925|s2cid=224931341 |url=https://hal.archives-ouvertes.fr/hal-02990620/file/MARMIC_2020_33_Original_V0.pdf }} an interval of at least 15 million years.
