This paper presents the results of many years of search for fossils that were discovered at the Mineral Raw Materials Mine in Mielenko Drawskie West Pomeranian Province, Poland. The most common fossils found in this mine are Ordovician trilobites of the genera Asaphus Brongniart, 1822, and Megistaspis Jaanusson, 1956, and Ordovician nautiloids of the genera Endoceras Hall, 1847, and Orthoceras Bruguière, 1789. Other fossils, such as: graptolites, bactritids, belemnites, ammonites, corals and various types of gastropods and bivalve molluscs, can also be found. The oldest fossils discovered are the Cambrian trilobites of the genus Agnostus Brongniart, 1822. This mine has fossils ranging from the Cambrian to the Quaternary. These fossils were transported in erratic boulders across the ice sheet from Scandinavia. Currently, the mine extracts gravel and sand, as well as stones and erratic boulders on an industrial scale, which are then crushed and used as building material in the form of aggregate.
