If you are looking for the official Sample Data for GPlates, included automatically with the Linux installation but not for OS X or Windows, it is available from the Sourceforge site.
GPlates 1.2 download folder – gplates-1.2-sample-data.zip
I am including a list of files here (below the break) in case others like me were wondering where they got some data. I am not responsible for these data, I just needed to re-download them and couldn’t find the source.
