What one-ton lizard used to live in Australia?

While reading Guns, Germs, and Steel, I came across an interesting tidbit about the large animal life that used to exist in Australia:

Sweet Zombie Jesus, a one-ton lizard?! What the heck was this thing? Do we have some artist concept art somewhere? Are the bones on display? If we don’t have bones, what is the proof behind this big fella? My google-fu fails me.

See here on the Wikipedia megafauna page.

A giant goanna. Like an overgrown Komodo dragon.

I’m astonished these haven’t shown up on a cheesy sci-fi channel movie.

Not quite the real Megalania, but close.

It is interesting to note that the first natives of down under could well have seen this monster.

Saw 'em. Killed 'em. Cooked 'em.

Crocodile Ton Dee??
