@Helloandgoodbye,
Anyone can come up with silly "interpretations" but since the reversals are also correlatable with other magnetic mineral content that have reached a Curie temp and have impressed normal or reversed polarities in the same time periods. These normal and reverse polarities have caused to be developed the GPTS (Geomagnetic Polarity Time SCale). part of the reversal is a time period wherein the field strength of one or another polarity and declintion lose strength and direction within a few thousand years. Then, when the reversal is attained, it stays that way to about a million years .

Theres several hundred more of the real science papers on correlation via geomag. Im sure any one of the workers could straiten out you Creationist popular science writers
The limitation of geomagnetics is that the latest interval of continental "drift" has somewhat overprinted earlier magnetic reversals determined by cooling magnetic minerals and iron ,nickle, Titanium , and cobalt containing rocks.
So our most accurate reversal age data comes from the early Cretaceous forward.
As for the paper you linked, I scanned the references as well and I really dont know where those folks have their heads stuck up. Their logic and data is all completely wrongand the speculation (at best) is poorpy thought out. Im sure the stuff was self published and noone witha college geophysics degree edited it.
