M. lepisma-S. minor-A. reticularis Assoc., Lower Bringewood, Welsh Borderland (Silurian of the United Kingdom)

Where: England, United Kingdom (52.0° N, 3.0° W: paleocoordinates 27.9° S, 13.0° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Lower Bringewood Formation, Gorstian (427.4 - 425.6 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; bioturbated, calcareous siltstone

• "...little evidence of current transport except in occasional coquinas...The picture is one of sthe settling of suspended silt and clay under quiet, low turbulence conditions below wave base and away from the shore. BA 3. Beds are notably calcareous."
• "...bioturbated calcareous siltstone facies of the mid-shelf..."

Size class: macrofossils
