Semirostrum ceruttii Variante:Imprimado feeding on low plants andSemirostrum ceruttii was a fossil odontocete belonging to Phocoenidae, the porpoise family, known from marine Pliocene deposits in California, United States. Formally described by Racicot and colleagues in 2014, this taxon represents one of the most extraordinary forms in porpoise evolution because of its extremely elongated lower jaw, which projected far beyond the upper rostrum. Its generic name may be interpreted as half rostrum or half beak,
