(CNN)Between 4500 and 2500 BC, the bodies of a couple, believed to be married, were placed carefully side by side in an ancient burial site of the Harappans, one of the world's earliest civilizations.
Ancient lovers found in Indian burial site mystify and intrigue archaeologists
Thousands of years later, in 2013, a team of Indian and South Korean researchers began excavation work in the necropolis now located in Rakhigarhi -- around 100 miles northwest of India's capital, New Delhi -- in a bid to extract DNA from the skeletal remains.
They discovered dozens of skeletons during the excavation process, which ended three years later. Their finds included the couple, the scientists said in a study published in the peer-reviewed ACB Journal of Anatomy. They believe this is the first Harappan pair confirmed to have been buried together.
