The article presents the results of archaeological excavations conducted in 2018 in the upper reaches of the Bolshoy Salym river on the left tributary of the third order that is the Samsonovskaya river. As a result, 19 objects of archeology are identified and examined. On the territory of four monuments, significant damage was recorded during the construction of ground communications of the Vuemskoye oil field. Damaged objects of cultural heritage namely Samsonovskaya 5, Samsonovskoe 12, Samsonovskoe 13 are studied by excavations. As a result, it was determined that all archaeological structures were the remains of hunting pits. The carried out isotope analysis of coal samples made it possible to distinguish two periods of their functioning: the middle of the 2nd century – the middle of the 3rd century and the end of the 12th century – the middle of the 13th century. The publication presents new data on the economic and commercial objects of the early Iron Age and the Middle Ages.

The Svyashchennaya Kedrovaya Roshcha (Sacred Cedar Grove) is an archaeological ensemble, located on the territory of the Khanty-Mansi Autonomous Okrug – Ugra. It includes several objects of different times: the Kintusovskoe 13 settlement (the 2nd–1st centuries BC), the Svyashchennaya Kedrovaya Roshcha burial ground (the 4th–7th centuries) and the Sotem-te-ike sanctuary (12th– 13th – the middle of the 20th century). As a result of excavations of the burial ground, the authors investigated the origins and use of the bear image in the culture of the inhabitants of Salymsky Krai, and memorial services which have been recorded since the end of the 4th century. After the burial ground gradually had ceased to function, the ritual activity resumed only in the 12th–13th centuries with the use of the Sotem-te-iki sanctuary by the Salym Khanty and lasted till the middle of the 20th century.

Tyv-ega-1 is an archaeological site in the basin of the Bolshoy Salym river, which is a tributary of the Ob river. In the framework of the accepted scientific archaeological periodization, the signs of ceramic vessel ornamentation make it possible to determine the belonging of the settlement to three stages of the cultural and historical development of the population in the North of Western Siberia. These stages are Zelenogorsky, Relkinsky and Kuchiminsky. The introduction of new materials into scientific use allows us to perceive the generally accepted periodization of the archaeological era of the Early Middle Ages in a different way.

The species composition of the animals bone remains from the excavations of Sherkaly 1 settlement is given. The 2925 bones from 5 species of domestic and 13 species of wild mammals, 17 species of birds, 5 species of fish were identified. The hunting of large ungulates – such as reindeer and elk played main role in the economy of the medieval population. The people contained domestic horses, the meat of which was used as food. Dog breeding was developed. The most numerous were the brown bear, beaver, white hare, and fox. Bird hunting did not play a significant role in the economy of the settlement. The main object of fishing was a pike.

In 2019 in the course of excavations of the Tazovsky settlement-workshop of the 12th–14th centuries (Tazovsky District of the Yamalo-Nenets Autonomous Okrug) the archer’s protective gear-plate for wrist used during shooting was found. The plate is made of mammoth tusk. On the sides of the plate, there are holes for fastening. On the front side of the plate, there is a dot pattern. The archer’s protective gear was found not far from metallurgical furnace along with other finds among which are a bone knife, a bone spoon, and others. Similar plates are recorded in the cultural layer of objects of the archaeological heritage of Bukhta Nahodka and Nadymsky settlement. The introduction of these materials into scientific discourse is important for the study of the material culture of the Polar region population.

The study presents an archaeoparasitological analysis of 34 samples from the occupation layer of Nadymsky gorodok (a small town) located in the North of Western Siberia. The discovered eggs of trematodes such as Opisthorchis felineus, Alaria alata, and Diphyllobothrium sp. allowed reconstructing some life aspects of the Nadymsky gorodok’s population. Raw and/or undercooked fish has been the predominant food source for the townspeople and their dogs for at least 400 years. Territorial differences in the distribution area of the intermediary hosts of Opisthorchis felineus in the North of Western Siberia could be the basis for the reconstruction of migration and economic relations of the local population.

The article is devoted to the gambling board game "Tavlei" (aka "Backgammon", "Shesh Besh" in the East and "tric-trac" in Europe), known in Russia from the 14th–15th centuries, and in Siberian cities and ostrogs (forts) from the late 16th to 18th centuries. The archaeological evidence about this game is examined. The evidence was found during the excavation of the Mangazeya settlement and other Russian Siberian towns and forts: bone chips, or checkers, dice, and the unique mangazeiskaya discovery that is the first in Russia tavlei board (the early 17th century).

The article and the publication of the archive document to it (excerpt from the official Voivodeship document "City list of Surgut of 204") show the architectural and defensive appearance of Surgut at the end of the 17th century. City lists of the late 17th century are of particular value for they contain a retrospective summary of information on the history of the construction or replacement of city walls and their parts, topographic data, and give the exact dimensions (in fathoms) of the length of the Surgut ostrog and the distances between the ostrog towers. According to these data, a large-scale scheme of the city and ostrog fortifications is made. The comparison of the scheme to the drawing from the "Drawing book of Siberia" by Semyon U. Remezov is presented. An attempt to link the scheme of city fortifications with the modern map of Surgut is made.

The article describes a fragment of a windowsill filling made of muscovite. The fragment was found during excavations of the archeological monument "Beryozovskoye Gorodishche" (a town) for restoration at the cultural heritage site of regional significance "Wooden bridge on ryazh (cribs) across the Kultichny gully (second half of the 19th – 20th centuries)". The size of the fragment and its preservation allows us to make a scientifically based reconstruction of the mica filling of the window opening. This is important for understanding the material culture of the population of Beryozov in the 17th–19th centuries.

The article examines the baptismal crosses that were found in the excavations of Beryozovskoe gorodishche (a town) in 2019. Their comprehensive analysis allowed us to give detailed typological and chronological characteristics of certain types of crosses and identify their analogies.

The article publishes materials obtained during the archaeological excavations of Ugutskoe 21 selishche (a village) and Ugutskoe 40 selishche for the first time. It is found out that this is one settlement that functioned in the 17th – early 18th centuries and belonged to the Ostyaks of the Yuganskaya volost in the Surgutsky Uyezd. The paper presents data on the planning structure, architecture, clothing complex, as well as paleozoological materials. Previously, this settlement was identified with the Yameltsov yurts, later with the Ugotsky ones.

The archaeological and botanical analysis of samples from the Russian town of Beryozov is made. The town of Beryozov is situated in the subzone of the north taiga woodlands in Western Siberia. As a result, from 29 plant samples and 8 samples of the occupation layer, more than five thousand remains of fruits and seeds, 27 taxa of plants are identified. Lists (seed complexes) of plants for each sample species are obtained, the macro-residues of which are found in the occupation layer of the posad part of the town. In the samples, the most common seeds of food plants growing in the vicinity of the city are lingonberries, blueberries, crowberries, Arctic raspberry, cloudberries, raspberries, bird cherry, and cedar. Cultivated cereals are represented by oat, which were brought from the southern regions. Hop seeds and hazelnuts were brought to the city from the European part.
