I like the old version better.
Ooohhh, there was so much more coastline to be had. I wonder if coastal property and water views were affordable back then.
Do you suppose we could go back to that...?
I was born just a couple of million years too late. I’d have had beach front property.
Reunite Gondwanaland!
So if you lived in Baker, Calif., Rhyolite, Nev. or Yuma, Ariz. at the time, you would have had beach-front property.
All you’d need are a tall ship and fair winds. Lots of exploring to do!
Oh sure, lots o’coastline, but they didn’t have the Oprah Winfrey Network’s quality programming back then!!

I would have had my own island!
He’s not even close. Geologists made a bad assumption fifty or so years ago.....
Here’ is what happened:

My wife was watching one of those “celebrity house” shows, and one of them had a big wall/fireplace made of imported sandstone. I told her ours was imported sandstone, too. She asked where it was from, and I told her “Pangea”.
In all fairness, it is rather unfortunate that such maps end with the present day. It would be as creative a project to show, based on current tectonic trends, what the future holds.
For example, in a mere 50 million years, Africa is going to jam headlong into Eurasia, as the most dramatic change.
At 150 million years, Australia will join with Antarctica, yet likely have a land bridge to Eurasia. And at 250 million years, the continents are generally going to Pangea-up again.
This is fantastic! “Annals of the Former World”, by John McPhee describes a lot of this, but I always had a hard time visualizing it well. Love it, love it, love it. Thanks for the link!
-——this is a concept that non-geologists really have problems with, because they don’t understand the processes of how continents get uplifted and subside ——
So there we have it....... global warming is not causing the sea levels to rise. The continent is subsiding as it moves.
Chicken little must be reeducated. Quacky Lacky must develop a program to curtail continental drift.
This is not theory but reality. They have the drift numbers and proof, not models.
