Coordinates: 2.0° South, 54.0° West (view map)
Paleocoordinates:68.9° South, 29.4° West
Basis of coordinate:estimated from map
Geographic resolution:local area
Time
Period:Devonian Epoch:Middle Devonian
Stage:Eifelian 10 m.y. bin:Devonian 3
Key time interval:Eifelian Other zone: Alpenachitina eisenacki
Age range of interval:393.30000 - 387.70000 m.y. ago
Stratigraphy
Formation:Maecuru Member:Lontra
Stratigraphic resolution:member
Stratigraphy comments: Member spans Emsian - Eifelian, but the dense beds of shelly fossils are from the top of the formation (Grahn 2005).
Lithology and environment
Primary lithology:hummocky CS sandstone
Secondary lithology:bioturbation siltstone
Lithology description: "The Maecuru Fm. of Emsian/Eifelian age is composed by the Jatapu and Lontra members...Jatapu [consists of] bioturbated silty/shaly layers and argillaceous sandstones...Fluvial sandstones and conglomerates are the main constituents of the Lontra unit. However, locally on the N flank and throughout the subsurface the uppermost Lontra sediments are shallow marine "tempestites", i.e. hummocky cross-stratified sandstones containing the well known Devonian invertebrate fauna recorded by pioneer workers from outcrops of the Maecuru and Curua rivers."
Environment:marine indet.
Geology comments: Deposition reflects deepening. See lithology description.
Taphonomy
Modes of preservation:body,cast
Size of fossils:macrofossils
Collection methods and comments
