Geography
| Country: | Czech Republic |
| Coordinates: | 49.5° North, 13.5° East (view map) |
| Paleocoordinates: | 49.6° South, 55.2° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | local area |
Time
| Period: | Silurian | Epoch: | Pridoli |
| 10 m.y. bin: | Silurian 2 | *Epoch: | Late/Upper Pridoli |
| Key time interval: | Pridoli | ||
| Age range of interval: | 423 - 419.2 m.y. ago | ||
| * legacy (obsolete) database fields | |||
Stratigraphy
| Formation: | Pozary | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Type locality is in Monograptus parultimus and M. ultimus Zones (which would make it early Pridoli). "Although this assemblage is typically developed in the Early Pridolian, its less diversified analogies are traceable in coarser biodetrital layers even higher, up to the Monograptus transgrediens Zone. | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal,gray lime mudstone |
| Secondary lithology: | calcareous "shale" |
| Lithology description: "The fauna is contained in well bedded, play grey bituminous finely biodterital and biomicritic limestones alternating with subordinate calcareous shale interbeds." | |
| Environment: | marine indet. |
| Geology comments: "Fossils are mostly fragmented, sorted and accumulated in thin layers reflecting higher energy pulses and changing circulation succeeding the Basal Pridolian Transgressive Event, probably BA 3 and 4." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Taxonomic list comments:For the most part, only trilobites are listed to genus level, but many other groups reported present. | |
