Litoceras is a trocholitid (Tarphycerida) genus that has been found in the Lower and Middle Ordovician of Newfoundland. Whorls in Litoceras have a broadly[ clarification needed] rounded cross section with its width greater than its height. Litoceras somewhat resembles the tarphyceratid Pionoceras from the same time, except for the siphuncle[ clarification needed] being dorsal and in the center.
Species within the genera Litoceras include: [1]
