Bhirrana
Bhirrana, also Bhirdana and Birhana, (IAST: Bhirḍāna) is an archaeological site, located in a small village in the Fatehabad district of the north Indian state of Haryana. Bhirrana's earliest archaeological layers contained two charcoal samples dating to the 8th-7th millennium BCE, predating the Indus Valley civilisation, but occurring in the same levels with Hakra Ware pottery which had been dated to the 4th millennium BCE in other sites of the region, as well as "about half a dozen" other charcoal samples from the early levels of Bhirrana dated 3200-2600 BCE, and smelted copper artefacts indicating a Chalcolithic rather than Neolithic stage of development.
