Our waterfront roundsman surprised the Little Darwin inmates when he discovered moonstones while prowling about North Queensland looking for items of interest .
These spherical or ovoid geological concretions, also known as moon rocks, dinosaur eggs , paddy rocks and snow men , found in the Richmond Shire, famous for dinosaur digs in an area dubbed Kronosaurus Korner, sometimes have fossilised bones and remains of fish and shells inside .
They come in a variety of sizes , from a golfball to boulders weighing several tonnes .
