Re: Prior to Gondwana?

["Randy King, go player and all-around swell guy!" <rking@flir.com>]

Scientific American had a good article on the subject withing the past 4
or 5 months.  Prior to recent research, nothing was known on the subject.  
If you need more specifics, I'm sure its is still lying around somewhere. :-)
