Antrigoulia
Antrigoulia is an extinct genus of palaeospinacid shark from the Cretaceous period. It is named after a farm in the vicinity of the type locality called Mas d’Antrigoule. It is known from a single species consisting of isolated teeth from the Valanginian of France, A. circumplicata. The name is derived from the concentric folds on the labial side of its teeth.
