Paleocoordinates:30.7° North, 17.5° East
Basis of coordinate:based on political unit
Geographic resolution:local area
Time
Period:Devonian Epoch:Early/Lower Devonian
Stage:Emsian 10 m.y. bin:Devonian 2
Key time interval:Late/Upper Emsian
Age range of interval:398.30000 - 393.30000 m.y. ago
Stratigraphy
Formation:Shanda Horizon Member:Lower Shanda Beds
Stratigraphic resolution:formation
Stratigraphy comments: Here are the subdivisions of the Telengitian Stage in type locality. Authors correlate stage roughly with Emsian, but note that the Salairka Horizon is said to correlate with the dehiscens Zone, which, according to Harland et al. 1990 is Pragian.
JA: originally entered as Emsian; the inversus zone is late Emsian

Lithology and environment
Primary lithology: lithified "reef rocks"
Secondary lithology: lithified "limestone"
Lithology description: Beds in type sections divided into a number of facies and subfacies: A: "consists mainly of biogenic-clastic limestone." A1: "coral limestones interbedded with siltstones and mudstones containing plant remains" A2: "massive reefal limestones" / "biogenic-clastic limestones, locally with coral bioherms" B: "composed chiefly of mudstones" B1: "interbedded with limestones and richly fossiliferous" B2: "barren" C: "consists of bedded, platy, clayey limestones locally marked by traces of subaqueous slumping" D: "may be equated with a sandy-muddy member with abundant plant remains"
Environment:reef, buildup or bioherm
Geology comments: Initiation of Telengitian marked by transgression, and termination by regression. Smaller cycles within the stage.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:biostratigraphic analysis
Taxonomic list comments:Material listed includes fish, plants, conodonts, ostracods, brachiopods, and rugose corals. Bryozoans, trilobites, tabulate corals, and crinoids are also known from these sections, but these have not been studied as completely and are not reported here.
