A.'reticularis'-L.depressa-S.euglypha Comm., Upper 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: Upper Bringewood Formation, Gorstian (427.4 - 425.6 Ma)

• Especially lower third. Authors give age simply as Ludlow. Assignment to Gorstian based on correlation chart in ref. 6658.

Environment/lithology: marine; bioturbated, calcareous siltstone and wackestone

• Inner shelf. ..shells mainly disarticulated...essentially an epibiont fauna, but bioturbation indicates some infauna...absence of thinkly laminated, dark beds indicates well oxygenated, normal turbulence level, BA 3
• ...calcareous siltstones with wackestone nodules, lensoid and lenticular in form, coalescing into units up to 3 m thick....intense bioturbation

Size class: macrofossils
