Actinopteria innotata Community in the Chelm borehole, eastern Poland (Silurian of Poland)

Where: Poland (53.2° N, 23.5° E)

• Paleocoordinates: 3.6° N, 36.5° W (Wright 2013)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Monograptus perneri zone, Pridoli (423.0 - 419.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; calcareous mudstone

• "Shallow, influenced by current activity."
• "Disarticulated shells occur on bedding planes of dark, calcareous mudstone."

Collection methods: Despite distribution, text seems to imply that all faunal elements are found at type locality.
