The paper describes the most meaningful stages of developing paleontological and stratigraphic research at SNIIGGiMS. For more than 50 years, SibRISC has developed regional pre-Cambrian and Phanerozoic stratigraphic charts of Siberia of several generations, which form the basis of geological prospecting and exploration. A dramatic reduction in public financing in 1990s depleted the geological industry; the scientific and methodological quality of regional works decreased; the requirements to the quality of data became less strict; changes in the structure of the Geological Service resulted in disarrangement of the hierarchy of stages of creation, testing, and introduction of the main stratigraphic models in geological prospecting. The stratigraphic charts of a number of time sections, approved by ICS, have not been revised for more than 35 years, but the ICS Bureau has discussed and approved 16 regional charts for the recent four years. These charts are planned to be published. The new-generation regional stratigraphic charts need to be published as soon as possible, this primarily concerns the Upper pre-Cambrian and Cambrian charts of the Siberian Platform interiors. It is impossible to improve the quality of stratigraphic framework without improving the methods of stratigraphic research. More intense integration with sedimentological analysis, with reconstructing the evolution of entire sedimentary paleobasins, and with modelling of processes occurred therein is a promising way.
