Cannibalism in Naticidae from the La Meseta Formation (Eocene, Antarctica)
Abstract Polinices marambioensis is a naticid gastropod which is the most common constituent in fossil accumulations in the upper section of the Cucullaea I Allomember (Middle Eocene) of the La Meseta Formation in James Ross Basin, Antarctic Peninsula. This species was an important predator of infau...
