Abandoned phosphorite mine Jan 1 (Cretaceous of Poland)

Also known as Annopol

Where: Annopol, Poland (51.8° N, 20.6° E: paleocoordinates 41.3° N, 19.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Albian (105.3 - 99.6 Ma)

• Lower part of unit 3, upper upper Albian

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, glauconitic, brown, sandy phosphorite

• Unit 3 was deposited during a late late Albian transgressive pulse, in a shallow-marine, highly productive and phosphogenic environment.
• Unit 3 is ca. 50 cm thick, dark greenish in color, and is composed of quartz sand with abundant glauconite, passing gradually upward into a quartz-glauconitic marl (Fig.1(A)). A distinct horizon replete with dark brown phosphatic clasts and fossils occurs in the upper part of this unit.

Size classes: macrofossils, mesofossils

• Articulated parts of the carapace of a Protostegidae gen. - the vertebral shields of epidermal shell (see text for further explanation).

Collection methods: surface (in situ)

• From a condensed, phosphate-rich mid-Cretaceous succession as exposed along the limbs of a small anticline.
