Manitoulinoceras
Extinct genus of molluscs
Manitoulinoceras is a genus of Late Ordovician oncocerid nautiloid cephalopods, found in North America. The shell is cyrtoconic, exogastric, more strongly curved than in Kindleoceras. The cross-section is somewhat wider than high, with a somewhat flattened upper side, known as the dorsum. Actinosiphonate deposits in the siphuncle are confined to the early part of the phragmocone.
