Tabulate coral-Stromatoporoid bioherm Comm., Rytteraker Fm. at Vallerkroken (Silurian to of Norway)

Also known as Reef 1803

Where: Norway (59.8° N, 10.4° E: paleocoordinates 24.2° S, 8.5° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Rytteraker Formation, Aeronian to Aeronian (440.8 - 433.4 Ma)

• Upper parts of formation.

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; peloidal, shelly/skeletal grainstone

• "...grainstone interpreted as very shallow, high-energy..."
• "The main substrate...is massive, more or less uniform, coarse, bioclastic grainstone...The matrix,which averages 50-65% of the buildups, contains micritized fragments and peloid packstone."

Collection methods: List based on type locality, but author states that it seems to be representative.
