Acastella elsana-A. tiro Zone fauna of Strzelce IG-2 section (Devonian of Poland)

Where: Poland (50.5° N, 21.1° E)

• Paleocoordinates: 15.0° S, 10.5° E (Wright 2013)

• coordinate based on political unit

• local area-level geographic resolution

When: Bostów Formation, Lochkovian (419.2 - 410.8 Ma)

• PJW: should be Bostów formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; gray, calcareous claystone

• "...grey claystones, somewhat marly, their carbonate content increasing upwards, and the associated fauna becomes more abundant and diversified..."

Size class: macrofossils

Collection methods: core

• Because faunal lists not complete for A. tiro zone (said mainly to be similar to A. elsana fauna), I have combined the two zones.
