Photo of the Ordovician - Silurian boundary, an example of marine transgression as exposed on the Southern tip of the Hovedøya island, Norway. Due to the folding of the caledonian mountain range, the layers have been inverted, leaving late Ordovician brownish mudstone with limestones nodules deposited in shallow water on top of the deep-water dark Silurian shale.
