You've done a fantastic job here - just thought that I would let you know that the site Riversleigh/Naracoorte Caves, which you have marked in Queensland, Australia, is actually two sites (you're half correct). Riversleigh is in Queensland at the area you have marked, but the Naracoorte Caves are in South Australia...now if I knew how to find it and post you the coordinates I would, but I am just a newbie.
