Sainte-Barbe Clays Formation
From Wikipedia, the free encyclopedia
The Sainte-Barbe Clays Formation is a geological formation in Belgium. It is found in localised areas of the northern margin of the Mons Basin, alongside the equivalently aged Hautrage and Baudour Clay Formations.[1] It is Upper Barremian-Lower Aptian in age.[2] It predominantly consists of laminated clay, with some lignite.[3] It is well known for the "Iguanodon sinkhole" locality near Bernissart where many specimens of Iguanodon bernissartensis were described by Louis Dollo in the late 19th century.
