Abstract

The Bromacker locality in Thuringia, Germany is world famous for its exceptionally well-preserved early Permian tetrapod footprints. In this paper, we provide the first detailed description of the Bromacker specimen with diadectomorph footprints that was donated to the National Museum Prague in 1916. The specimen shows more than 80 footprints of six trackways and several incomplete step cycles of different morphological qualities assigned to the ichnotaxon Ichniotherium sphaerodactylum. Apart from its paleoichnological value, the slab is of historic interest as it fits into a long period of about five decades (1908 to 1954) from which there is almost no information on fossil discoveries at the locality.

Abstract

New material of fish fossils from the west part of Most Basin is described here. Disarticulated and articulated fish remains were discovered in several layers in the Holešice and Libkovice members. Fossil fish occurrence, their taxonomic structure and taphonomy were evaluated in the context of the sediments. The data indicate that conditions in the lake, which formed when the coal swamp was flooded, were variable. Most of the time, the water was well oxygenated; occasionally the oxygen saturation was reduced to hypoxia and even anoxia. Conditions subsequently changed, and the lake became well oxygenated. Especially in the Libkovice Member, the fish-containing layers appear to be characterized by relatively quick sedimentation.
