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.[3] The initial remains were discovered in 1859 after an ornithopod tooth was found in a piece of coal in a dump outside the mine by Professor Ferdinand Stoliczka, and the productive seam discovered thereafter. The first material was described by Emanuel Bunzel in 1871[4] and then additional material was described by Harry Seeley in 1881.[5] Due to mining activity in the area ceasing at the end of the 19th century, no additional remains have been recovered since.
Referred to by the dubious name ‘Megalosaurus pannoniensis’[5] Nearly identical to teeth known from the Csehbánya Formation[10]
Flora
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.[11][12][13]
