In this article we present the results of a study of the fragments of 60 vessels found at 23 sites in the Tuymaada Valley by an archeological expedition of Yakutsk State University. Cogged and figured stamping characterizes the decoration of the Early Iron Age ceramics in Yakutia. The preliminary classification is based on 31 decorative elements created by stamping and incising. The elements are divided into four main groups: 1) cogged; 2) figured; 3) incised ; and 4) stick-impression to imitate a twisted cord. Regarding techniques of decoration, three types of ceramics are defined: waffle, ribbed, and plain. In addition, two main groups of stylistic decoration are defined: ridge and non-ridge. Horizontal rows of similar decorative elements are the main motifs. In turn, the decorations form compositions of several (2 - 4 and more) rows of stamps.

Analysis of the paste was conducted using a number of vessels and a number of sites where these pots were found. The structure of decorative compositions and statistical analyses of the paste composition show very slight differences in the groups of smooth and toothed stamped decoration, and also between waffle, ribbed, and smooth-sided ceramics. This may reflect a unity of traditions in ceramic production (in fact, this implies cultural unity) or at least a succession of traditions or cultures.

The analyses conducted show that the ceramics of the Iron Age in the Tuymaada Valley are quite homogenous. This clearly implies a monolithic culture. The studies of the Early Iron Age of the Tuymaada Valley have just begun.
