The Akbauyr petroglyph-tamga is located approximately 1 km north of the Akbauyr archaeological complex. The sign was engraved on a relatively flat, horizontally oriented natural rock surface.

The tamga consists of three clearly incised lines forming a single intersecting composition. The main design is formed by diagonal lines intersecting at an angle, creating a configuration that resembles the letter “H” in shape. The central part of the sign is particularly pronounced: the lines are more deeply incised and show evidence of repeated tracing along the same grooves. This feature may indicate that the contours of the sign were deliberately retraced and deepened during its execution.

The sign was produced on the rock surface by incision using a sharp tool. The depth and width of the individual grooves vary. The dimensions of the sign are 8.60 × 7.30 × 7.91 cm.

Based on the available evidence, this petroglyph-tamga may tentatively be attributed to the Early Iron Age.

This tamga sign is noteworthy for its resemblance to the Ergenekti tamga of the Naiman tribe of the Middle Zhuz.
