You are in the polar forests of Australia, 115 million years ago.

The air was damp and surprisingly chilly for a forest, smelling strongly of wet ferns and pine. You have been tracking the subtle movement through the undergrowth of the Early Cretaceous Victorian landscape, trying not to snap any of the twigs beneath your boots.

Then, you saw a flash of mottled brown and green darting between the undergrowth. It was small, roughly the size of a turkey, standing on two sturdy, kangaroo-like legs. A Qantassaurus.

It paused, perhaps fifteen feet away, its large eyes blinking, taking in its surroundings. Its face was unexpectedly short and stout, a "blocky" snout that set it apart from its slenderer relatives. It didn't seem threatened, just incredibly alert. It twitched, its long tail—stiffened for balance—jerking as it prepared to move again.
