Atrypoidea Community, Late Ludlow-Early Pridoli, Lithuania (Silurian to of Lithuania)

Where: Lithuania (56.0° N, 24.0° E: paleocoordinates 15.3° S, 1.1° E)

• coordinate based on political unit

• basin-level geographic resolution

When: Ludlow to Ludlow (427.4 - 419.2 Ma)

Environment/lithology: marine; gray limestone and black marl

• "...assigned to BA 2. According to P. Lapinskas, gray, nodular limestones with black marl interbeds occur on the back side of bioherms, indicating shallow, relatively quiet water conditions. The A. Comm. occurs in dark-colored, bituminous beds, whereas the Herrmannina Comm. occurs in light colored interbeds, with both sandwiched about the bioherms. Most of the Atrypoidea are disarticulated..."
• "Occurs in nodular, gray and dark-gray, coarse-grained, commonly stromatoporoidal limestone with interbeds of black marl belonging to the second facies zone."

Collection methods: Several localities combined. Table 21.11 gives abundances for brachiopods species.
