The main lithology is clay, marl, siltstone and sandstone, with a minor conglomerate component.

All remains have been found at a single locality, which is a thin marl seam in the Konstantin mining tunnel, within the Felbering Mine in the Neue Welt area north west of Muthmannsdorf in Lower Austria.

[5] Due to mining activity in the area ceasing at the end of the 19th century, no additional remains have been recovered since.

Most of these specimens were recovered from mining dumps near Grünbach am Schneeberg in lower Austria.

The flora of the formation is considered to represent that of a high humidity subtropical climate, typical of the Euro-Sinian phytogeographical region.
