Abstract: The article studies a new genus of stromatolites, Severinsaaria unica gen. nov., which was discovered on the Karelian craton of the Fennoscandian Shield. The stromatolites were found in carbonate rocks from the Upper Jatulian section of the Paleoproterozoic period, on the southwestern coast of Lake Segozero, in the Central Karelian stromatolite province. The study used various methods, such as optical and electron microscopy, graphic preparation, and 3D visualization using Blender software. Severinsaaria was compared with other columnar stromatolites from the study area, such as Djulmekella and Segosia, to identify its unique characteristics. The discovery of Severinsaaria allows expanding our knowledge of the diversity of Paleoproterozoic stromatolites on the Karelian craton, and better understanding the paleontological features of the Central Karelian province.
