Thank goodness

I imagine that there were some monsters that early man determined too dangerous to coinhabit the earth with.
And that's when caveboys became cavemen.

Megalania?
Isn't she married to Donald Trump?

Fuck. No. Megalania mainly went extinct do to its prey items going to extinct due to climate change. Megalania undoubtedly hunted humans for food as they had no real ways of defending themselves. Aborigines at the time would've only had fire-hardend spears with no stone tips, which wouldn't do much of anything against a 20 foot venomous monitor lizard.

Imagine coming off ya front patio and seeing that shit (if it was still alive that is)
