• A family of ammonoid cephalopods or goniatites, in typical forms being rotund and involute with the lateral sutural lobes and saddles relatively simple. It is of Carboniferous age and is strictly synonymous with the division Goniatitidæ.
• The Magdalenian period or Glyptic of Piette has been further divided by him into two great epochs, the Eburnean or time of the mammoth, going back into glacial times, when the men lived who carved the likeness of that animal on its tusks, and the Tarandean or reindeer epoch, when the climate had ameliorated, but when reindeer still lived in the south of France and were hunted by a more advanced type of mankind.
