Gondwana became Australia, Antarctica and India

Jo Wittaker, Sydney University geophysicist says that the fossils of creatures in the sunken parts of Gondwana found off the coast of Australia show that the land was once part of the megacontinent and were not created by undersea volcanic activity. She called it

an exciting discovery which would hopefully shed light on how Gondwana broke into present-day Australia, Antarctica and India between 80 and 130 million years ago.

Since Australia is considered a remnant of the lost continent of Lemuria Mu, the discovery of these sunken parts of Gondwana could be undersea remnants of Lemuria Mu.

Possible parts of the lost continent of Lemuria discovered off the coast of Australia

It was once a megacontinent. It encompassed present-day Australia, Antarctica, and India. We call it Gondwana.

Parts of the submerged portions of Gondwana were found a month ago off the cost of Australia. Rocks on the underwater “islands” show fossils that once existed in shallow coastal waters, not in their present location, 2,000 meters or 6,600 feet–more than a mile–below the ocean floor . These submerged islands had likely once been above water.

Were they once part of the lost continent of Lemuria?
