Determining the exact age of the Keuper succession in Upper Silesia, southern Poland, as well as understanding the sedimentary environments are of paramount importance, particularly with regard to the famous discoveries of vertebrate remains, including early dinosaurs.
The major goal of the project "The evolution of terrestrial environments of the Upper Silesian Keuper as biotopes of vertebrates" (N N307 11703) was an exhaustive, integrated study of the bone-enriched middle Keuper interval in terms of stratigraphy, sedimentology, mineralogy and geochemistry. This website presents results of the project, granted for Grzegorz Racki by the Ministry of Science and Higher Education, and realized in Polish Academy of Sciences, in Institute of Paleobiology (2009–2010) and Institute of Geological Sciences (2011–2013). However, the achievements are only a starting point to comprehensive presentation of the Keuper themes, jointly with photographic documentation of sections studied and extensive regional literature.
