The article discusses the results of archaeological research in 2019-2020, conducted on the territory of the village of Selitpennoe in the Astrakhan Region, which overlaps the cultural layer of the Selitrennoe settlement. The characteristic of excavations and pits with the most expressive finds is given. The distribution of archaeological material and numismatic finds in chronological and topographical aspects is analyzed. Two previously unknown urban necropolises and a pottery workshop discovered in the course of research are localized. The dynamics of changes in the area of the medieval city in the 14^th -15^th centuries is presented. The analysis of the coin case shows the predominance of coins of the 1330s-1350s and the products of the Sarai al-Jedid mint. It is proved by archaeological methods that there is no cultural layer of the 13^th century under the modern village. As a result of the materials obtained, the Selitrennoe settlement is identified by the author with the capital of the Ulus of Jochi, the city of Saray al-Jedid.
