Where: Poland (50.7° N, 17.2° E: paleocoordinates 51.0° N, 16.4° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Miocene (11.6 - 5.3 Ma)
• Beetle-bearing silica deposits are younger than the Przeworno fauna, but older than the clays filling the cave which contain an Upper Miocene or Pliocene pollen assemblage. Age of the fossil beetles may be determined as Upper Miocene.
• bed-level stratigraphic resolution
Environment/lithology: fissure fill; lithified chert
Size classes: macrofossils, mesofossils
Preservation: original chitin
Collection methods: Repository: Institute of Geology, Warsaw University
