“…Preliminary age correlations derived from ammonites found with latest Cretaceous mosasaurids from Jordan are compiled by Jagt et al (2018), and show that the uppermost Maastrichtian Muwaqqar Chalk Marl Formation incorporates several marker species that are diagnostic for the middle/upper Maastricht Type Formation in the Maastrichtian type area of the The Netherlands. Stratigraphical correlations with the upper part of the Kunrade Formation also bolster observations of closely-related mosasaurid taxa in these units.…”
