Geologic formation in Netherlands / From Wikipedia, the free encyclopedia
The Breda Formation (Dutch: Formatie van Breda; abbreviation: BR) is a geologic formation in the subsurface of the Netherlands. The formation consists of marine glauconiferous sands and clays that were deposited during the Miocene epoch. Although the formation is not very rich in fossils, sometimes bones of fishes, mammals (Leptophoca cf. proxima, Protophocaena minima),[1] shells and shark teeth (a.o of megalodon) are found.
