Kotelnich the uniqueness of the landmark, the only comparable sight being Karoo, South Africa. Annually Russian and foreign scientists find skeleton fragments and bones of ancient animals of the Permian period of Palaeozoic era, Triassic and Jurassic periods of Mesozoic era. Paleontological museum of Kotelnich was opened in 1994. It exhibits both the findings from the excavation site in Kotelnich, and the replicas of the most famous findings from Germany, the USA, and Mongolia. The exposition of the museum shows the global geological and evolution processes that took place on Earth about 200 million years ago. The workers of the museum
South Polar region of the Cretaceous temperatures caused by the high amounts of carbon dioxide and possibly methane greenhouse gases in the atmosphere. This caused a lack of permanent ice coverage in the polar regions, though the carbon dioxide level dropped between 115 and 66 million years ago (mya), possibly allowing some permanent ice cover. It is possible that, throughout the Cretaceous, several small ice sheets developed. Increased tectonic activity, causing more geothermal heat, may have prevented glaciation and increased global temperatures. Temperatures may have been up to 15 °C (27 °F) warmer than they are in the modern age. The landscape of the Middle Jurassic
