What is the significance of Deadman Lane in relation to Harappan Civilisation?

The lane was named after the discovery of a skull and bones.

Deadman Lane, a narrow alley ranging from 3 to 6 feet in width, acquired its name due to the discovery of human remains in the area. Part of an adult skull, bones of the thorax and upper arm, and fragments of a tiny skull were found in fragile condition at a depth of 4 ft 2 in. The body was positioned diagonally across the lane. In 1925, sixteen skeletons were unearthed in the same vicinity, still adorned with their ornaments at the time of their death.
