Koninckioceratidae
Encyclopedia
The Koninckioceratidae comprise a collection of nautilid
genera, typically with more or less evolute shells with depressed whorl sections, that are combined as a family within the Tainocerataceae
. As perceived, the Koninckioceratidae contains 11 genera and lasted from the Early Mississippian to about the end of the Permian.
Koninckioceratidae was established by Hyatt in Zittel, 1900, to include Edaphoceras, Endolobus, Foordiceras, Lophoceras, and Temnocheilus, with Knightoceras, Milkoninckioceras, Subvestinautilus, and Valhallites since added by Kummel (1964)
The Konnckioceratidae is essentially a Mississipian (L Carb) family with only four of the nine genera found in Mississippian age rocks extending as far as the Permian and one reaching only into the Pennsylvanian (U Carb). Only two genera are known exclusively from post Mississippian formations, Knightoceras from Middle Pennsylvania and Foordiceras from Permian. This is opposite from the development of the Tainoceratidae
in which the number of genera expands in the Permian and Triassic from a more feeble beginning rather than diminishes.
Genera, listed by earliest known age, are:
Nautilida
The Nautilida constitute a large and diverse order of generally coiled nautiloid cephalopods that began in the mid Paleozoic and continues to the present with a single family, the Nautilidae which includes two genera, Nautilus and Allonautilus, with six species...

Tainocerataceae
The Tainocerataceae is a superfamily in the cephalopod order Nautilida characterized by straight to loosely coiled shells, generally with a degressed, such that the width is greater than the height, to quadrate whorl section. Many bore spines, ribs, frills, wings, or nodes...

Tainoceratidae
The Tainoceratidae is a family of late Paleozoic and Triassic nautiloids that are a part of the order Nautilida, characterized by large, generally evolute shells with quadrate to rectangular whorl sections...
in which the number of genera expands in the Permian and Triassic from a more feeble beginning rather than diminishes.
Genera, listed by earliest known age, are:
- EdaphocerasEdaphocerasEdaphoceras is koninckioceratid genus and nautilid from the Mississippian of North America, named by Hyatt, 1884, with depressed whorls just in contact. The shell, as typical for the family, is evolute; whorl section is fusiform with broadly rounded venter and dorsum meeting at a narrow angle on...
Miss. N Am. - LophocerasLophocerasLophoceras is a Nautilid genus belonging to the tainoceratacean family, Koninckioceratidae, found in Lower Carboniferous sediments in Europe, and named by Hyatt, 1893. The shell of Lophoceras is evolute, large, with a slight impressed zone on the inner rim...
Miss. Eu - SubvestinautilusSubvestinautilusSubvestinautilus is an evolute koninckioceratid genus, order Nautilida, with a depressed, trapezoidal whorl section. The venter is broadly rounded, ventrolateral shoulders sharply rounded, flanks flattened and converging toward a narrow rounded dorsum. In early growth stages a keel forms on the...
