7. Cihelna v Bažantnici (Claypit in the Pheasantry) Natural Monument (PP)

The former claypit in Hloubětín beyond the railway bridge. Cadastre: Hloubětín. Area: 4.38 ha. Elevation: 238-270 m above sea level. Established by the Ordinance of Prague Municipality No. 5/1988 of July 4, 1988.

Geological stratptype, exposure of Cenomanian claystones with rich fossil flora.

One of the most important exposures of the Peruc and Koryčany formation of the Bohemian Cretaceous with fossilized prints of plants of Drynaria tumulosa, Nehvizdya obtusa, Myricanthium amentaceum and Myrtophyllum genitzii species. No soil cover has developed.

Plant communities are mostly of ruderal character: white melilot (Melilotus albus), common melilot (Melilotus officinalis), mugwort (Artemisia vulgaris). However, there are also rarer species, such as the large-flowered mullein (Verbascum thapsiforme). The tree level bordering the margins is dominated by the silver birch, accompanied by the common oak, the hornbeam, the sycamore, and false acacia. The shrub level is represented by dense elder undergrowth.

Beetles are represented by the Bembidion milleri, Ophomus puncticolis and Amara pulpani species, the butterflies by the meadow brown (Maniola jurtina). The grass snake has been observed. The area is a nesting site of black redstart (Pheonicurus ochruros), in the past also of the little owl (Athene noctua). Minor mammals are represented by the white-toothed shrew (Crocidura russula).

It is necessary to maintain the geological profile accessible for observation and research.
