TSU scientists have discovered soil and plant remains dating back more than 300 million years

A unique type of soil was found during a joint expedition of employees of the Department of Soil Science and Ecology Biological Institute, Geology and Geography Department specialists, and university students. The purpose of the trip was their zonal practice. One of the places of the route of the expedition was the north shore of Big Belyoe Lake. There, researchers discovered rocks that were the ancient soil of the Devonian period.

- This finding is unique, such cases are rare, - says Oleg Merzlyakov, one of the expedition participants, an assistant professor of Soil Science and Soil Ecology in the Department of Biological Institute TSU. – The Devonian is the fourth period of the Paleozoic Era. It began more than 400 million years ago and lasted about 60 million years. This period was very rich in biotic events. Life developed rapidly and developed on land.

During the laboratory studies of soil monoliths brought from Khakassia, we found the remains of ancient plants - archaeopteris. These are primitive horsetails that were among the first out of the sea to the land. Moreover, we find not just individual small fragments but representative systems - shoots, leaves, and large trunks.

Recently, TSU scientists have finished their study of the ancient finds. The study formed the basis of the description of Devonian fossil soil in northern Khakassia. There were no such scientific works, so it is unique.
