Eocanites ruani - a new ammonoid species from the Gattendorfia-Stufe (Early Carboniferous) of
Saalfeld in the Thuringian Mountains.

  Eocanites ruani a. sp. is one of the earliest representatives of the genus Eocanites (nodosus species
  group with a concave venter in mature stages). lt seems to be a ribbed descendent of Eocanites
  holcoventris RUAN 1981 known only from southern China (Wangyu, Guizhou).  Present reords are
  restricted to a narrow level in the Pfaffenberg member of the Saalfeld region, corresponding to the
  upper part of the Acutimitocers aeutum zone (early Gattendorfia subinvoluta zone).  This is a
  conodont age of latest Siphonodella sulcata zone and of basal Eurly Siphonodella duplicata zone
  (or Siphonodella bransoni zone).
