Ecclimadictyon cystosum-Favos. moyeroensis Comm., Lwr Klenova Fm., Novaya Zemlya (Silurian of Russian Federation)

Also known as Reef 1020

Where: Russian Federation (71.0° N, 58.0° E: paleocoordinates 0.6° S, 0.6° W)

• coordinate estimated from map

• basin-level geographic resolution

When: Lower Member (Klenova Formation), Sheinwoodian (433.4 - 430.5 Ma)

• Upper Lower Klenova Formation.

• group of beds-level stratigraphic resolution

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

• "[Set of two related communities]: Developed in marginal part of extensive shallows with mobile sediments containing structures indicating a lot of physical transport, belonging to different facies and dense benthic populations forming biostromes and coquinas. [This community]: Dense populations of stromatop's and tabulates formed buildups in marginal part of extensive shoal areas under influence of agitated waters (skeletal debris and pellloides set in an algal-calcareous matrix). Solitary rugose corals show evidence of burial in life position (overgrown by stromatop. but with no evidence of transport)...Comm. lived on crinoid debris flows...Biostromes."
• "Dark-gray, medium-laminated skeletal packstones."

Size class: macrofossils
