We here describe the first lungfish tooth plate from Las Flores Formation, Chubut, southern of Argentina. This is the youngest ceratodontid known in the continent. In Africa, ceratodonts disappeared in the Eocene. Afterwards, they are only known in Australia until their extinction during the Pleistocene. The Las Flores tooth plate also represents the southermost lungfish known since the Coniasian (early late Cretaceous).
