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/Tertiary boundary deposits.

Comparative assessment justification:
The Palaeocene of the section is equivalent to the Palaeocene deposits of Kamienny Dół, a nearby locality, where the first Polish find of a Lower Palaeocene crocodile Thoracosaurus comes from.

Protection status and accessibility:
Documentary site of inanimate nature protected since 1992. The area of Kazimierz Landscape Park. The outcrop is easily accessible.

Character of site: Abandoned quarry.

Area: 1 ha

Altitude: 150 m a.s.l.

Lithology: unspecified

Discipline: Palaeobiology, Palaeoenvironment, Stratigraphy of Phanerozoic

Process Age: *all periods

Bedrock Age: Cretaceous, *all periods

Description of primary interest:
The abandoned quarry in Bochotnica (Ścianka W i K Pożaryskich) represents a rare for central Europe, section containing the Maastrichtian/Palaeocene boundary. The section provides opportunity to study the boundary with excellent exposure and accessibility of the boundary interval. The composite nature of the boundary reveals much of the history of the latest Cretaceous - earliest Palaeocene of the area. It is an excellent exposure to study the taphonomical processes. The whole succession is highly fossiliferous.
