Diagnosis
ReferenceDiagnosis
B. Kröger 2007Slightly cyrtocone graciloceratid with angle of expansion of 13 . Piersaloceras differs from all other Graciloceratidae in having crenulated frills and longitudinal ribs. Cross section of conch is nearly circular or slightly de−
pressed. Adult body chamber is tubular, less curved than juvenile growth stages. Similar to other Graciloceratidea Piersaloceras displays thin tubular siphuncle, positioned between centre and conch margin at convex side of curvature of growth axis. Sutures are straight or with very low lobe at flanks. Septal spacing is narrow, septal curvature shallow. Septal necks are achoanitic or very short suborthochoanitic. Siphuncle is slightly expanded within chambers. No endosiphuncular deposits are known (after Teichert 1930)
