Encrinuroides-Pseudoproetus Assemblage, Kap Schuchert, Greenland (Silurian of Greenland)

Where: Greenland (81.0° N, 65.0° W: paleocoordinates 5.3° N, 29.8° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Cape Schuchert Formation, Aeronian (440.8 - 438.5 Ma)

• Monograptus triangularis to M. convolutus biozones.

• formation-level stratigraphic resolution

Environment/lithology: offshore shelf; black, calcareous, cherty/siliceous mudstone

• "Level-bottom carbonate shelf...BA 4-5...It is possible that it was deposited in inter-carbonate mound basins of no great lateral extent, in which circulation was restricted; such an environment of deposition is also presumed for all Otarion and Aulacopleura dominated assemblages."
• "The lithology is thinly bedded, cherty, black, bituminous, calcareous mudstone."
