Remarks

The extent and content of genera in the family Trigonoceratidae has been repeatedly debated over the past few decades, and several very different views have been expressed (e.g., Flower & Kummel 1950; Shimansky 1957, 1967; Kummel 1964; Dzik 1984; Histon 1999). Differences of opinion are partly related to the treatment and evaluation of the poorly understood family Koninckioceratidae Hyatt in Zittel, 1900. In this context, two genera ( Temnocheilus M‘Coy, 1844 and Endolobus Meek & Worthen, 1865 ) are particularly problematic and have been assigned to different families by different authors. For example, Temnocheilus has been placed in the families Temnocheilidae Mojsisovics, 1902 , Koninckioceratidae , and Tainoceratidae Hyatt, 1883 . However, the great resemblance to Vestinautilus Ryckholt, 1852 and other members of the family Trigonoceratidae suggests that Temnocheilus should also be included in this family.
