I remember American Indian bone tools found that DATED TO 21,000 YEARS AGO! All the news papers ran with the story!
Then several years later was a small article buried in the back of a newspaper, the the items were actually only 2000 years old.
Also another story that due to an ancient blast from the sun, all radiocarbon datings were not as old as said but actually 500 years younger than originally said to be.
Wonder how many other datings are in error.
And the three do lunch on Fridays.
Ah....Grant money is forever.
