| Coordinates: | 7.0° South, 38.0° West (view map) | ||
| Paleocoordinates: | 75.1° South, 22.1° East | ||
| Basis of coordinate: | estimated from map | ||
| Geographic resolution: | small collection |
Time
| Period: | Devonian |
| 10 m.y. bin: | Devonian 1-5 |
| Key time interval: | Devonian |
| Age range of interval: | 419.20000 - 358.90000 m.y. ago |
Stratigraphy
| Formation: | Ponta Grossa Shale | ||||
| Stratigraphy comments: Polar, "austral" fauna. Listed as Eifelian in age. Sampled over 3.7 meters |
Lithology and environment
| Primary lithology: | fine,micaceous poorly lithified "shale" |
| Secondary lithology: | lithified siltstone |
| Lithology description: Finely-laminated, micaceous, soft, waxy, purplish and yellowish shale with minor interbedded siltstone and layers of fine-grained sandstone | |
| Environment: | prodelta |
| Geology comments: Caster mentions influence of glacio-fluvial deposition, but Simoes et al. (GSA 1998, 1999) talks both interpret the setting as "at (or below) storm wave base" in a "platformal environment". Petri and Fulfaro (GEOREF: 1966) mention lithology | |
