This is the stone fill or erosion in the east part of the room of LGR:025 underneath Locus:7585:204
It mainly consists of stones and burned mudbrick fragments that measures 5-10 cm in diameter approx.
It is on level with Locus:7585:207 and Locus:7584:053
The layer was thin lentil shaped, like a depression in the middle of the room. It is still visible in the E baulk in 7585.
This is probably a depression made from a filling and the stone, being heavier, will roll further towards the middle.
When looking at the W-profile, it seems like this layer could have extended over most of the surface, but was so shallow that it was not recognisable in the plan, only the center of the "lentil" was thick enough to be noted
