Geography
Country:Argentina
Coordinates: 29.5° South, 68.5° West (view map)
Paleocoordinates:50.3° South, 65.6° West
Time
Period:Carboniferous Epoch:Late/Upper Mississippian
Stage:Serpukhovian 10 m.y. bin:Carboniferous 3
Key time interval:Arnsbergian
Age range of interval:326.40000 - 318.10000 m.y. ago
Stratigraphy
Formation:Guandacol
Stratigraphic resolution:group of beds
Stratigraphy comments: Basal part of the Guandacol Formation (in the earlier sense, not including the Aguas Blanquitas that may be considered as the basal member). Middle part of formation dated as earliest Bashkirian (c. 320-321 Ma from U/Pb ages), and lower part dated at 326 Ma (Valdez et al. 2020), suggesting a Serpukhovian age for the insects.
Lithology and environment
Primary lithology:planar lamination,black lithified claystone
Environment:marine indet. Tectonic setting:pull-apart basin
Geology comments: Interpreted as lacustrine environment but presence of brachiopods indicates that it is actually marine
Taphonomy
Modes of preservation:mold/impression
Size of fossils:macrofossils
Collection methods and comments
Reason for describing collection:taxonomic analysis
Collection method comments: Repository: Paleoinvertebrate Division of the Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" (MACN-In)
