In their research, scientists analysed paleomagnetic lava as well as ancient limestone they discovered in Italy. The analysis showed that the Earth's crust moved around 3 degrees every million years.
An international team of scientists claims our planet tipped over to one side 84 million years ago. According to the results of their study, published on 15 June in the scientific journal Nature, the Earth tilted by 12 degrees between 86 and 79 million years ago. This change moved New York City to Tampa, Florida said the study's co-author Sarah Slotznick.
If this detail alone is not extraordinary, researchers revealed that after tipping over, the Earth righted itself. "We never suspected we would see this full round-trip event", said Ross Mitchell, a geophysicist at the Chinese Academy of Sciences and Slotznick's co-author.
Researchers say mantle plumes located from the outer core towards the Earth's crust could have triggered the changes. Per another hypothesis, the tilt may have been prompted by the shifting of tectonic plates, which scientists say started around 84 million years ago. This change could have altered the balance of our planet, said Ross Mitchell.
Since Nature is peer-reviewed, their peers are gonna have a field day with that assertion. If the Sputnik article is an accurate representation, the thesis goes utterly and entirely against a whole host of sciences - physics, geology, and plate tectonics just for starters.
While the tectonic plates do shift and migrate, the crust as a unit does not. It moves in bits and pieces, called "plates", at various rates. While the earth's axis does "wobble" over time (from about 25 degrees tilt to around 15 degrees tilt), it never dos so suddenly - that would violate the laws of physics and conservation of angular momentum, not to mention rip the crust asunder and destroy the planet.
Plate movements at the rate of 3 degrees per million years is a bit optimistic, I think. They didn't just suddenly start moving 84 million years ago - they've been moving all along. For example, where I sit now is about 37 degrees north latitude, but 325 million years ago it was about 5 degrees south of the equator. Someone at Sputnik may have taken the 1 inch per hundred years spread of the Atlantic Ocean as a constant rate, and that may not have been in the original article at all - which is why I wonder at the accuracy with which Sputnik reported the original article.

Diogenes was eating bread and lentils for supper. He was seen by the philosopher Aristippus, who lived comfortably by flattering the king.
Said Aristippus, ‘If you would learn to be subservient to the king you would not have to live on lentils.’ Said Diogenes, ‘Learn to live on lentils and you will not have to be subservient to the king.’
