To begin to see where Au. sediba might fit on the family tree, researchers pinned down the age of the fossils by dating the calcified sediments surrounding them with advanced uranium-lead dating techniques and a method called paleomagnetic dating, which measures how many times the Earth's magnetic field has reversed.
-
To come up with an age, they used a technique known as paleomagnetic dating, which takes advantage of the flip-flop of Earth's magnetic field every several hundred thousand years.

~ Studies of ancient supercontinent don't match up -- "For a quarter-century or more, the prevailing view among geoscientistssupported by paleomagnetic records in rockhas been that the portion of the ancient supercontinent of Pangea that is now the Colorado Plateau in southern Utah shifted more than 1,300 miles north during a 100-million-year span that ended about 200 million years ago in the early Jurassic Period, when Pangea began to break up."
