Campanian and Maastrichtian sphenodiscid ammonites from southern Nigeria by P M P Zaborski. Publication date Usage Attribution-Noncommercial   Sphenodiscid ammonites were widespread during the Maastrichtian, with records from localities in Africa, Europe, and both Americas.

Outside North America, however, their record is rather scattered. The genus is known from Maastrichtian sediments in western Europe, in the lower Maastrichtian of India and in the upper Maastrichtian of Poland and Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): ersitylibrary (external link)   Co Young, K.

ZABORSKI Department of Geology, University of Ilorin, Nigeria Abstract--It is possible to correlate the late Campanian and early Maastrichtian marine strata of The crude fourfold division of the Campanian in current use reflects the sporadic occurence of ammonites in narrow zones and our ignorance of the true systematic position of most species.
