Post-Acastella tiro Zone Lower Bostovian fauna of Strzelce IG-2 section (Devonian of Poland)

Where: Poland (50.5° N, 21.1° E: paleocoordinates 41.9° S, 56.7° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

Environment/lithology: marine; gray, calcareous claystone

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

Collection methods: core

• Because complete faunal lists are not given for each level (some levels are said to have fauna similar to others) I have agglomerated several levels post-dating the Acastella tiro zone but still within the Lower Bostovian.
