Dozens of megalithic jars have been discovered in Assam, India, at four new sites, a new study published in the Asian Archaeology journal has found.
Ranging from one to three metres tall, some of the jars have decorative carvings and others are plain, according to the study coauthor Nicholas Skopal, a doctoral candidate at Australia National University in Canberra.
Whilst 65 jars have been identified so far, it's thought many more could be buried underground.
