Megacrioceratinae

Megacrioceratinae is an extinct ammonoid cephalopod subfamily. It has been described as family Megacrioceratidae in 2006, but later changed into subfamily under its current name.[2] Ammonites belonging to this subfamily lived from Plesiospitidiscus ligatus zone of Upper Hauterivian until Avramidiscus kiliani zone of Lower Barremian.[1]
