Furuberget locality, Furuberget Fm (Ordovician of Norway)

Where: Norway (60.8° N, 11.0° E: paleocoordinates 31.1° S, 9.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Furuberget Formation, Sandbian (458.4 - 453.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: basinal (siliceous); gray shale and limestone

• slightly deepened basin within the photic zone (algae and trilobites with large eyes), and below the storm wave base. The high portion of siliciclastic components infers a placement of this basin not far away from land or a delta system.
• the base of the Furuberget Formation is in a gradational sequence from the grey shales of the underlying Hovinsholm Formation to green/grey shales with limestones

•and calcareous siltstones.

Size classes: mesofossils, microfossils
