Atrypoidea prunum Comm. in E Baltic (Silurian to of Estonia)

Where: Estonia (58.3° N, 22.5° E: paleocoordinates 14.0° S, 1.0° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Ludlow to Ludlow (427.4 - 419.2 Ma)

Environment/lithology: marine

• "In the E Baltic A. prunum occurs in patchy lenses, where adult specimens may be in life position. IN the subsurface of the E Baltic, A. prunum dominates over other brachiopods within extensive intervals that have been interpreted as inshor shoal and open shelf sediments (Nestor & Einasto 1982; Kaljo & Rubel 1982). The beds w/ A. prunum have been assigned to BA 2, nearer to the shoreline than the similar environment of the Homoeospira-Delthyris Community (Kaljo & Rubel 1982, table 2.3)."

Collection methods: Epifauna on brachiopods mentioned but mostly not listed (hederellids, spirorbids, aulaporids).
