Teichertoceras

Systematic Paleontology

Class: Cephalopoda

Subclass: Nautiloidea

Order: Discosorida

Family: Westonoceratidae

Genus: Teichertoceras

Teichertoceras is a discosorid within the Westonoceratidae from the middle Ordovician of North America with a endogastric curvature in the earlier portion of the phragmocone. Its origin may lie in Ulrichoceras, as does that of Sinclairoceras and Simardoceras. Teichertoceras probably gave rise to Westonoceras, which in turn gave rise to Winnipegoceras, and to Faberoceras.

As with other westonoceratids, Teichertoceras probably spent much of its time on or over the sea floor facing forward in search of prey or shelter.
