Antrigoulia circumplicata

Antrigoulia is an extinct genus of palaeospinacid cartilaginous fish from the Cretaceous period of France. The generic name refers to a farm in the vicinity of the type locality called Mas d’Antrigoule where isolated teeth were found in Valanginian-aged marine strata, A. circumplicata. The specific name is derived from the concentric folds on the labial side of its teeth.
