This is the first place I have seen this Dinosaur but doing some research reveals an interesting animal. I wonder why some people think it would have had a club or spikes on the back of its tail? It is sad that Australian Dinosaurs are not so well known; I guess the Aussies should start making Dinosaur movies!

There is an interesting book by John A Long called "Dinosaurs of Australia and New Zealand and Other Animals of the Mesozoic Era" which helps a lot in discovering that dark prehistoric corner of the Messozoic.
