What it says
Divers mapped lines of dressed blocks and found many stone anchors, some triangular with three holes, of a kind used in the Bronze Age. On Bet Dwarka a seal of conch shell carved with a three-headed animal came to light. Rao dated the walls to about the 15th century BCE and identified them with Krishna’s Dvaraka; other scholars accept the structures and the anchors but argue over their date and use.
What it proves
The Mahabharata’s Mausala Parva says the sea swallowed Dvaraka after Shri Krishna left the world; here the seabed holds a drowned settlement at that very place.
