   Petro- and paleomagnetic methods are applied to the study of the upper part of the Late Pleistocene Tuzla section (Azov coast of the Taman Peninsula) composed of continental sediments and dated at 50-10 ka. The detailed curves of the angular components of the geomagnetic field obtained in this study display an anomalous direction coinciding in time (~25-35 ka) with an anomalous horizon discovered in rocks of the Roxolany section (Ukraine). According to the world time scale of geomagnetic excursions, the anomalous direction correlates with the Mono Lake excursion. A significant correlation between the time series NRM 0.015 /SIRM (Tuzla section) and NRM 250 /KB (Roxolany section) in the interval 50-10 ka and the world composite curves VADM-21 and Sint-800 implies that, in this time interval, the curve NRM 0.015 /SIRM reflects the variation in the relative paleointensity of the geomagnetic field.
