Came across this just now...

'About 140 million years ago 😁 Greater Adria—which later got shoved beneath southern Europe—was a Greenland-size landmass (submerged portions in gray-green) south of the continent'

'Forget the legendary lost continent of Atlantis. Geologists have reconstructed, time slice by time slice, a nearly quarter-of-a-billion-year-long history of a vanished landmass that now lies submerged, not beneath an ocean somewhere, but largely below southern Europe...'

'The only visible remnants of the continent—known as Greater Adria—are limestones and other rocks found in the mountain ranges of southern Europe'

'About 140 million years ago, it was a Greenland-size landmass, largely submerged in a tropical sea, where sediments collected and slowly turned into rock. Then, as it collided with what is now Europe between 100 million and 120 million years ago, it shattered into pieces and was shoved beneath that continent. Only a fraction of Greater Adria’s rocks, scraped off in the collision, remained on Earth’s surface for geologists to discover'

140 million eh, would love to see that tape measure!

It goes on, but I like this bit...

'The study is not the only evidence for Greater Adria as a lost continent. Other researchers who use seismic waves to generate computerized tomography–like images of structures deep within Earth have created an “atlas of the underworld”—a graveyard of slabs of crust that have sunk into the mantle. This research shows that portions of Greater Adria now lie as much as 1500 kilometers below our planet’s surface.

For 150 mil years, think 200 years or so IMO.
