Description
Ancestral uddenitins; conch similar to Uddenites, but venter flat. Suture characterized by tridentate primary external lateral lobe with all three subdivisions aligned with or slightly orad of base of adjacent ventral lobe. Ventral prong of external lateral lobe (L1.1(v) L1.1(v) ) broad; both subdivisions and primary umbilical lobe (U) may be bidentate. Three named species. [Overall geometry of the external lateral lobe of Prouddenites closely resembles that of presumed ancestor, the Serpukhovian pronoritid Uralopronorites. However, the dorsal lobe of Prouddenites is bidentate, similar to those of all
