A replica of the famous "Dancing Girl" from Mohenjodaro is found engraved on a potsherd in the form of a graffiti. The massive fortification wall of the town was made of mud bricks. The houses were made of mud bricks (sun-baked bricks). Wide linear roads can be seen separating the houses. A circular structure of baked earth is probably a "tandoor"- a community kitchen still seen in rural India. Presence of the baked bricks is seen used in the main drain provided on the width of the northern arm of the fortification wall to flush out the waste water from the houses. Dancing girl graffiti Pottery graffiti at Bhirrana show "mermaid" type deities and dancing girls; the latter have a posture similar to Mohenjo-daro's bronze "dancing girls" that the archaeologist L.S. Rao stated that "it appears that the craftsman of Bhirrana had first-hand knowledge of the former." These deities or dancing girls may represent apsaras, or water nymphs, associated with water rites once widespread in the Indus Valley civilisation. Other findings Other significant findings included terracotta wheels with painted spokes. People used to live in shallow mud plastered pit dwellings and pits were also used for industrial activity or sacrifices. Multi-roomed houses were exposed at this site, one house with ten rooms and another with three rooms. Another house had a kitchen, court yards, chullah [i.e., chulha, cooking stoves] in the kitchen; beside the chullah, charred grains were also found. According to Rao, all phases of Indus Valley Civilisation are represented in this site.
