Geography
Country:Canada State/province:Newfoundland and Labrador
Coordinates: 53.3° North, 60.3° West (view map)
Paleocoordinates:36.5° South, 71.0° West
Basis of coordinate:based on political unit
Geographic resolution:local area
Time
Period:Cambrian Epoch:Series 2
10 m.y. bin:Cambrian 2-3
*Period:Early/Lower Cambrian - Middle Cambrian *Epoch:Caerfai
*International age/stage:Atdabanian - Lenian
Key time interval:Dyeran Trilobite zone: Bonnia-Olenellus
Age range of interval:514.80000 - 511.00000 m.y. ago
* legacy (obsolete) database fields
Stratigraphy
Formation:Forteau
Stratigraphic resolution:group of beds
Stratigraphy comments: 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).
Lithology and environment
Primary lithology:burrows,shelly/skeletal lithified wackestone
Lithology description: finely laminated biomicrite-sparite with some minor terrigenous admixture containing macrofossil sements/fragments, interlayed with cement.
Environment:reef, buildup or bioherm
Taphonomy
Modes of preservation:original calcite,original silica
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:bulk,field collection
Reason for describing collection:paleoecologic analysis
Collection method comments: 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.
Taxonomic list comments:It should be noted that for some organism groups, such as trilobite, only some of the genera are identified, mostly for biostratigraphical correlation. The ranking corresponds to the following: 1 - rare, 2 - common, 3 - abundant.
