Two of them – 'Sailugem' and 'Ulandryk' – are located in close proximity to each other on the northern slope of the ridge Sailugem, the third section – 'Argut' – located on the slopes of Katun and the North-Chu ridges. The concentration of carbon dioxide in the atmosphere reached maximum in the last 15 million years, scientists from the University of California at Los Angeles found that the concentration of greenhouse gas CO2 (carbon dioxide) in the Earth's atmosphere reached a record over the past 15 million years. Atmospheric concentration of carbon dioxide may be associated with such environmental changes as the distribution of glaciers, wind intensity and the population of the ecosystem. New study first showed that the estimate atmospheric CO2 concentrations in the deeper past of the planet by using the ratio of isotopes of calcium and boron in sedimentary rocks, which include the remains of microorganisms living in surface waters greenhouse gases could lead to significant climatic disasters. Scientists have learned, when the butterfly Researchers from the University of Turku managed to lift the veil of secrecy and to determine when the Earth emerged Butterflies. Earlier on past butterfly biologists knew practically nothing, because fossils of their precursors were detected.

Now scientists have moved in the previous study of butterflies. Scientists studied four kinds of individuals who provided all the main lines of the family of Brush-footed Butterflies. Butterflies were collected with the help of amateur entomologists and scientists from many countries. To reveal the time separation of one group of Brush-footed Butterflies other required fossils of their ancestors, but because they are missing, remains of flowers have been studied, serving food source for ancient butterflies.
