1681A-3, Beatrix LXX, 371.7-387.0 m; Dijkstra's collection, Netherlands (Paleocene to of Netherlands)

Also known as Beatrix State Mine, Netherlands, depth 371.7-387.0 meters; Beatrix-70

Where: Maasniel, Netherlands (51.2° N, 6.0° E: paleocoordinates 47.9° N, 2.3° E)

• coordinate based on nearby landmark

When: Late/Upper Paleocene to Late/Upper Paleocene (58.7 - 33.9 Ma)

• This locality is either upper Palaeocene or Palaeocene/Eocene boundary. Downhole of this locality are marine limestones assigned to the Early Palaocene (Montain). The Montain has now been formalized as the Swalmen Member of the Landen Formation. This collection is from the same locality as 1680 (PBDB 34404).

Environment/lithology: terrestrial

• The borehole is derived from lithologies that include grey, variegated, and sandy clays, fine grained sands, and browncoals (i.e. with 'continental' or 'limnic' aspect).

Size class: microfossils

Preservation: original sporopollenin

Collection methods: core,

• This collection is on two slides. Many specimens of Azolla teschiana are in one slide. The other slide contains tangled clumps of debris held together by 'hairs' (modern); some megaspore apparatuses.
