Rybičková rock

Rybičková rock is a small but scientifically significant nature reserve located northeast of Oslavany, west of the village of Neslovice, within the cadastral territory of Padochov (a part of the town of Oslavany) in the Brno-venkov district, near Zbýšov. Covering just 0.0511 hectares, it ranks among the most important paleontological sites in Moravia.

What is hidden inside this rock?

Rybičková rock is a former quarry wall roughly forty metres long, sitting at an elevation of 305 to 320 metres above sea level. It consists of alternating layers of greenish-grey claystones, siltstones and fine-grained sandstones belonging to the Padochov formation. These sedimentary layers date back to the late Paleozoic era, specifically the Permian period, and have attracted the attention of geologists and paleontologists for decades as they study the deep history of the region.

Why is this site protected?

The rock's primary claim to protection lies in its outstanding paleontological value. It preserves imprints of plants and fish that are hundreds of millions of years old, and research conducted on site has repeatedly yielded new material for scientific study. Rybičková rock was declared a natural monument on 11 December 1980, a designation that reflects how long ago its scientific importance was recognised.

Fish fossils from millions of years ago

The most striking discovery associated with this site is the abundance of ray-finned fish fossils. In 2002, around 200 specimens of these fossilised fish were found in the vicinity of Rybičková rock. This find confirmed the site's status as one of the key locations for reconstructing the ancient aquatic ecosystems that once existed in what is now the Boskovice Furrow, millions of years before humans walked the Earth.

Geological significance of the region

The Boskovice Furrow, within which Rybičková rock is situated, is one of the most important geological and paleontological areas in the Czech Republic. This extensive tectonic depression accumulated sediment over long geological periods, and today it serves as a record of Earth's history stretching back hundreds of millions of years. The plant imprints and fish remains found in the rock layers of Rybičková rock help scientists better understand what life looked like in this area during the Paleozoic era, long before the age of dinosaurs.

Who should visit this site?

Rybičková rock is a particularly interesting stop for enthusiasts of geology, paleontology, and the natural history of the Rosice-Oslavany region, an area also known for its former coal-mining basin. While the rock itself is not a large-scale tourist attraction in the conventional sense, its scientific value makes it a unique stop on any sightseeing route through the area around Oslavany and Zbýšov. It is a place where visitors can literally see traces of life from millions of years ago, still preserved in the rock layers.
