Where: Newfoundland and Labrador, Canada (53.3° N, 60.3° W: paleocoordinates 36.5° S, 71.0° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Bonnia-Olenellus trilobite zone, Forteau Formation, Dyeran (516.0 - 513.0 Ma)

• The formation encompasses two series: lower series - begins stratigraphically only a few meters above the top of the underlying Bradore Sandstone; upper - biostromal series with less pronounced ""reef"" characteristics that occur and seperated from lower series by about 20m of interbedded siltstones, shales and sandstones. AGE: Waucoban; refined by A. Hendy (6/2009) on the basis of biostratigraphic data (= Bonnia-Olenellus zone). Further refined to Dyeran (PJW).

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, burrowed, shelly/skeletal wackestone

Size classes: macrofossils, mesofossils

Preservation: original calcite, original silica

Collection methods: bulk,

• SOme of the skeletons may have been derived as washed-in material from the outside; they may be sheletons that were attatched by fleshy tissue,, but whose attatchments rotted and the skeletons fell to the sediment; they may have been soft-bodied with hard parts, and attatched within the cavities, but whose bodies rotted, thereby depositing the skeletal debris on the cavity floor (e.g. sponges and their spicules); or, of course, some of the skeletal debris may represent organisms which actually lived in the sediments.
