Scientists discovered rocks off the coast of Brazil that could be part of a hidden continent.
Geologists took granite samples from the seabed near the Rio Grande Elevation, which is a long seismic mountainous ridge that runs across the Atlantic Ocean.
They now believe that the rocks are likely a portion of a continent that sunk to the bottom of the ocean when Africa and South America pulled apart from each other 100 million years ago. They have called the discovery "Brazilian Atlantis."
Brazil's Geology Service dug up the seabed two years ago so they could analyze rocks.
There were numerous granite rocks found on the seabed 900 miles from Rio.
"This could be the Brazilian Atlantis," Roberto Ventura Santos, a top official at Brazil's Geology Service said. "We are almost certain but we must bolster our hypothesis. We will have final scientific recognition this year when we conduct drilling in the area to retrieve more samples of these rocks."
In April, a team of geologists from Brazil and Japan boarded a submersible called Shinkai 6500 to study the Rio Grande Elevation.
It was there that they saw evidence of what Ventura called the Brazilian Atlantis.
"We began to see that the area could be a piece of the continent that disappeared into the sea millions of years ago," he said.
They are currently carrying out more tests on the rocks and on the geological formation.
