Goniatites maximus Münster, 1832 from Schübelhammer near Heinersreuth in Frankenwald. 

Opis

Diagnosis. — Two subventral lobes of the suture; compressed conch with ventrolaterally oriented spines at juvenile stages.

Remarks. — The suture of Sphenoclymenia is even more advanced in its subdivision than that in Gonioclymenia. On this basis Korn proposed to separate the genus in his family Sphenoclymeniidae.
