Geography
Country:United Kingdom
Coordinates: 51.5° North, 3.3° West (view map)
Paleocoordinates:14.6° South, 0.7° West
Basis of coordinate:estimated from map
Geographic resolution:small collection
Time
Period:Carboniferous Epoch:Early/Lower Mississippian
Stage:Tournaisian 10 m.y. bin:Carboniferous 1
Key time interval:Tournaisian Conodont zone: Pseudopolygnathus multistriatus - Polygnathus mehli
Age range of interval:358.90000 - 346.70000 m.y. ago
Stratigraphy
Geological group:Black Rock Limestone Formation:Friars Point Limestone
Stratigraphic resolution:formation
Stratigraphy comments: On a regional basis the lower-middle beds of the Friars Point Limestone span parts of the Zaphrentites delanouei - Caninophyllum patulum coral assemblage biozones of Ramsbottom and Mitchell (1980). These data place the Ty-nant fauna within the mid–upper part of the Tournaisian Series, probably close to the Tn2⁄Tn3 boundary of Belgian notation (i.e. close to the Hastarian-Ivorian Stage boundary; Conil et al. 1977).
