Sunken city

Evidence of a lost civilisation has been discovered off the coast of India.
Archaeologists have recovered carved wood, pottery, pieces of sculpture and
human teeth from a now submerged settlement in the Gulf of Cambay off Gujarat.
Radiocarbon dating of one wooden sample suggests the settlement is around 9500
years old. If the date is confirmed, the site would be the world’s first known
“city”. Until now, the earliest settlement of this size was thought to have
appeared in the Sumer Valley in Mesopotamia around 3000 BC.
