1.7-Billion-Year-Old Chunk of North America Found Sticking To Australia (livescience.com)
walterbyrd shares a report from Live Science: Geologists matching rocks from opposite sides of the globe have found that part of Australia was once attached to North America 1.7 billion years ago. Researchers from Curtin University in Australia examined rocks from the Georgetown region of northern Queensland. The rocks -- sandstone sedimentary rocks that formed in a shallow sea -- had signatures that were unknown in Australia but strongly resembled rocks that can be seen in present-day Canada. The researchers, who described their findings online Jan. 17 in the journal Geology, concluded that the Georgetown area broke away from North America 1.7 billion years ago. Then, 100 million years later, this landmass collided with what is now northern Australia, at the Mount Isa region.
"This was a critical part of global continental reorganization when almost all continents on Earth assembled to form the supercontinent called Nuna," Adam Nordsvan, Curtin University doctoral student and lead author of the study, said in a statement. Nordsvan added that Nuna then broke apart some 300 million years later, with the Georgetown area stuck to Australia as the North American landmass drifted away.

Isn't that why we sent the Australians over there in the first place?
The entire earth is all connected to itself and the planet is not flat after all. This is earth shattering news!
if trump would quit denying climate change, this stuff wouldn't happen.
Thatâ(TM)s mine!!! Give it back!!!!
Just wait. It's Global Warming's fault somehow
Dumping their crap on our own fair shores for billions of years... without even a thank you note.
I hope you Chooks turn into Emus and kick your dunny down.
Calling someone a "hater" only means you can not rationally rebut their argument.
For those of us that aren't geologists and saw "Nuna", but read/expected "Pangaea":

Here's how the continental drift *really* went: http://pbfcomics.com/wp-content/uploads/2016/09/PBF260-The_Drift.png
We must reclaim our land. Build a wall around it to keep our those deplorable Aussies.
#Trump2019 #MAGA â" including our newfound land!
... and propose drilling for oil by summer!
Trolling is a art,
So in a way Great Britain joined long lost siblings under the Commonwealth? Isn't that nice of them?
President Trump demands immediate return of American property. Unnamed private investor will be building a golf resort on it.
Of course news about a fake are Fake News.
Bad blood. It's thieves and criminals what were sent to Australia. So now they stole a piece of someone else's continent?
Enjoy life! This is not a dress rehearsal.
Who knew the aborigines were canucks?
Give it back goddammit!
Go see a doctor.
I find myself deeply moved in my faith that God would go to all this trouble to mislead idiot atheists into believing the world is more than 6,000 years old.
I must go at once to donate my children's college fund to Pat Robertson. You go, God!
I've calculated my velocity with such exquisite precision that I have no idea where I am.
In the related news, Canada has announced the annexation of the piece of Australian continent. Australian youth prepares for extended conflict in the bush and their parents taken for unannounced purposes. It's the Red-White-Dawn. Where will you be tomorrow when the war began?
Hey Australia! We want our land back!
They filled a international court motion to get their land back.
We call that the "sticky bit"
Just another day in Paradise
Has anyone made a klingon joke yet?
Make American Whole Again!
These exotic terranes, which are rock that originally were part of other continents, are a pretty common occurrence. Most of the eastern seaboard of the US was once part of Africa or South America. Large parts of Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina, North Carolina, Virginia, Delaware, New Jersey, New York, Connecticut, Rhode Island, Massachussets, New Hampshire, Maine Nova Scotia and Newfoundland contain African rocks. The contact between African and North American rocks runs through New York, Its called Cameron's Line. A large long piece of Africa called Avalonia broke off, drifted across the ocean and lodged on North America 400 million years ago. Florida and Louisiana was seperately added by the collisions that formed Pangea, it remained on the North American side when the split occured.
We want our rocks back!
Geez, don't tell Native Americans that. They'll be claiming it's theirs.
My understanding is that Continental Drift failed to gain acceptance due to a lack of information on what would cause the continents to move. It was based upon surface observations that made sense of the topography but little else.
When geologists understood the physics of the Earth's core and mantle, that provided the mechanism. It also explained volcanos, earthquakes, and large scale structures like the Mid-Atlantic Ridge, the Pacific Ring of Fire, and more.
This got all bundled together into Plate Tectonics and voilà! A successful geophysical theory.
Sorry mate your shit out of luck, you can't have it back we gave it to the aborigines years ago..
OK. I'll feed the troll.
Look at the Koran, the cook book of Islam. Then look at what they have done throughout history, and continue to do today.
That is EMINENTLY repeatable. Take any generation of Muslims. Allow them to read the Koran. An unhealthy number will
take it to heart and actually try to emulate Mohammed.
Now, for Christianity. I believe most people would find it most agreeable to emulate Jesus. You know, the guy who said
to love your neighbour, treat others as you wish to be treated, bless those who curse you. That's why Christians have
been doing a lot of praying lately. They see another encroachment on their lands, and this time it is so insidious as to
be almost impossible to stop. How can you stop the MSMs brainwashing of the idiot masses who have never read
enough history to see that yes, time and again, Muslims have adhered to their book of rules which green lights violence,
rape, and genocide.

when my background is from Korea, 'nuna' means older sister in Korean... and I have an older sister.

Acid rain destroyed many monuments and historic artifacts.
The criminals were sent to Australia and the Religious fanatics sent to the U.S.
