Probably interesting to a geologist but I'm not sure what relevance it's discovery has to the modern world.

Landmass "drowned" during continental breakup about 85 million years ago. Exciting!

Maybe Plato's Atlantis was there, instead of at Thera/Santorini which happened much later as a volcano explosion which triggered a tsunami hitting the Crete coast and destroying its fleet.

Researchers have found evidence for a landmass that would have existed between 2,000 and 85 million years ago.

I do not believe the "2,000" part literally means Roman Empire times. I think the writer(s) meant to say, lasted from 2 billion (2000 million) years ago to 85 million years ago. I believe this makes sense in the context of the mention of Rodinia, which broke up "750 million years ago" (i.e., nearly a billion).

If correct, your suggestion about Atlantis makes no sense. Atlanteans before the demise of the dinosaurs? I do not think so.

I was somewhat confused about that time frame reference too.

I was only saying that myths such as Atlantis contain often a glimpse of truth. What happened many years ago can happen again. All you need is the eruption of an underwater volcano such as Vavilov and Marsili in the Tyrrhenian Sea and it can happen again.

What happened then, millions of years ago, is still happening now today.
This movement will continue until such times as the earth's liquid core finally
solidifies.

The Kite Fliers

There is a good deal of vagueness about the supposed size of Atlantis in Plato's accounts. The only firm figure we have is his description of the plain of the largest island as extending 2000 by 3000 stadia or about 230 by 345 miles. This is considerably smaller than the usual sense of the word continent. Plato. at least some of the time, refers to Atlantis as an island. Any larger extent that seems to be implied may have been intended to refer to the reach of a group of islands.
Its interesting that Plato also seems to have a sense of what he calls a 'true continent' further West, which surrounds the Atlantic Ocean. Some mysterious knowledge of the Americas, or merely a coincidence? The Greeks at about this time apparently had a sense of a (spherical) world, much larger than the area surrounding the Mediterranean Sea.

Atlantis has been interpreted to refer to a number of different places in the world. Plato seemed to indicate its location in the Atlantic Ocean. If his reference to its being beyond the Pillars of Hercules (Gibraltar?) is considered insufficient, there is also his list of the ten kings of Atlantis to consider. Among these are the names Elasippos and Gadeirus. These seem to refer with reasonable clarity to place names very near or West of the Straits of Gibraltar. Elasippos is a very ancient name for Lisbon, Portugal, and Gadeirus seems to be the ancient Gades, today known as Cadiz, Spain.

During the last ice age, not so very different in time from the 9600 BC date given by Plato for Atlantis, the sea level was about 400 feet (~120 meters) lower than it is today. This would have exposed much larger areas of land around the Azores, Maderia, Canary Islands, and Cape Verde Islands. All are in the Eastern Atlantic, no so very far from the Straits of Gibraltar. It would be interesting to see what lies in the undersea sediments along those ancient shores, instead of just on the mountaintops we see today.

The old shorelines from the time of the ice age could be 100 kilometers or more from the nearest land, and beneath 120 meters of water. A rather remote location for divers to do underwater archaeology.
After nearly 10,000 years of the accumulation of sea sediments, it might take a good deal of excavation before anything could be seen. A 200 kilometer island could easily have well over 600 kilometers of shoreline to explore. Just where to look?
A very detailed sonar study of the sea bottom might find faint hints of something buried beneath the sea floor. This could help narrow down the search. I don't recall hearing of anyone trying to do this.

Pretty sure the Bermuda stuff is bunk.
Can't believe how many still talk about it, compared to other more substantial finds.
