Commune: Kazimierz Dolny (pow. puławski, woj. lubelskie)

Framework element or context represented:
Middle Vistula section of Upper Cretaceous and lowermost Palaeocene.

Primary geological/geomorphological interest:
Cretaceous/Paleocene boundary deposits.

Comparative assessment justification:
The succession from Nasiłów follows up, almost directly, the succession exposed in the quarry of Kazimierz (the marly horizon known from the top of the latter was excavated 5 metres below the base of the Nasiłów quarry). The boundary interval can be compared with the complete boundary succession as known from Stevens Klint in Denmark.

Protection status and accessibility:
Proposed to protection as documentary site. It is accessible including on didactic trail.

Character of site: Abandoned quarry.

Area: 2 ha

Altitude: 130 - 160 m a.s.l.

Lithology: unspecified

Discipline: Palaeobiology, Palaeoenvironment, Stratigraphy of Phanerozoic

Process Age: *all periods

Bedrock Age: Paleogene, Cretaceous, *all periods

Description of primary interest:
Besides historical quarry in Bochotnica the Nasiłów quarry is the only section in extra-Carpathian Poland, and one of the few in central Europe, spanning the Maastrichtian/Paleocene (Danian) boundary. Although the boundary is discontinuous, the succession still reveals most of the events from the terminal Cretaceous. The terminal Maastrichtian and the boundary interval itself is extremely fossiliferous; the succession above the boundary gives an excellent access to the basal Palaeocene (Danian) in the area, with still relatively rich macrofauna. Most of the macrofaunal groups both of the Maastrichtian and of the Danian were described monographically. The Nasiłów quarry is the type section of numerous taxa described.
