node minimum age |
Procerophis was recovered from a diverse snake fauna in the Cambay Formation, Gujarat, India. The Cambay Formation is minimally dated based on the occurrence of the planktonic foraminifera taxon Nummulities burdigalensis burdigalensis, which corresponds to Shallow Benthic Zone 10 (lower Cuisian, Serra-Kiel et al., 1998). SBZ 10 corresponds to planktonic foraminiferal zone P6b, which is middle Ypresian, approximately 53-50.5 Ma (Vandenberghe et al., 2012).
node maximum age |
Maximum age is for the early Maastrichtian based on the first occurrence of Caenophidia from the Wadi Milk Formation (Werner and Rage, 1999).
|primary fossil used to date this node|
Procerophis is assigned to Colubroidea on the basis of: elongate, narrow centrum and neural arch, paracotylar foramina, and an anteroposteriorly elongate neural spine that possesses a uniform width along its length.
