Cuban geologist Manuel Iturralde says that an examination of rock samples that will be collected in a few months should shed further light on what could be an ancient sunken city deep off Cuba?s coast.?These are extremely peculiar structures … They have captured all our imagination,? says Iturralde. ?If I had to explain this geologically, I would have a hard time.?

The remains of a huge underwater city off the western coast of India may force historians and archaeologists to radically reconsider their view of ancient human history. It?s believed that the area was submerged when ice caps melted at the end of the last ice age, 9-10,000 years ago.

Marine scientists say archaeological remains discovered 120 feet underwater in the Gulf of Cambay off the western coast of India could be over 9,000 years old. The vast city – which is five miles long and two miles wide – is believed to predate the oldest known remains in the subcontinent by more than 5,000 years.

Canadian researchers using a miniature submarine to probe the sea floor off the western tip of Cuba have discovered stone structures deep below the ocean surface that may have been built by an unknown human civilization as far in the past as 6,000 ago, about 1,500 years earlier than the great Giza pyramids of Egypt.

?It?s a really wonderful structure which looks like it could have been a large urban center,? says Soviet-born Canadian ocean engineer Paulina Zelitsky, of Advanced Digital Communications (ADC). She says the structures may have been built by unknown people when the current sea-floor actually was above the surface. Volcanic activity may have caused the site to sink to 2,100 feet beneath the Caribbean Sea.
