40,000 to 20,000 years ago
This large carnivore scavenged Diprotodon carcasses, Macropus, Procoptodon Goliah and Protemnodon and other prey that had died or were trapped in the mud springs. Megalania appeared about 1.5 million years until extinction some 40,000 to 20,000 years ago, with its closest living relative, the Komodo dragon.

The perentie (Varanus giganteus) is the largest monitor lizard or goanna native to Australia. It is the one of the largest living lizards on earth, after the Komodo dragon, Asian water monitor, crocodile monitor, and intersecting by size with Nile monitor.
Are there any Komodo dragons in Australia?
Komodo dragons have thrived in the harsh climate of the Indonesian Islands for millions of years. Fossils, from 50,000 years ago, show they used to live in Australia once upon a time! Due to the increasing threats of habitat destruction, poaching and natural disasters, these dragons are considered a vulnerable species.
How fast could Megalania run?
A study published in 2009 using Wroe’s earlier size estimates and an analysis of 18 closely related lizard species estimated a sprinting speed of 2.6–3 m/s (9.4–10.8 km/h). This speed is comparable to that of the extant freshwater crocodile (Crocodylus johnstoni).

the Lace Monitor

Is the mosasaurus real?
Mosasaurs are a group of marine lizards that would have lived in the Badlands area from about 75-69 million years ago. When they were alive, mosasaurs could reach lengths of up to 50 feet, which is roughly the length of a bus! Mosasaurs were top predators of the world’s oceans and would eat anything they could catch.
What is the Tingamarra swamp crocodile?
It belongs to an ancient group of crocodiles whose relationships to living crocodiles are unclear. Fossilised pieces of the skull and other skeleton parts of the Tingamarra Swamp Crocodile have been found at Murgon in south-eastern Queensland.

Alamitophis tingamarra was a small Eocene madtsoiid, an extinct family of primitive snakes known mainly from Gondwana. Madtsoiids have the longest fossil record of any group of snakes, with a record that stretches from about 90 million to 100,000 years ago.
What are the threats facing crocodile monitors?
The main threat facing crocodile monitors is loss of habitat resulting from deforestation from logging and the conversion of land for agriculture. This is of particular concern because crocodile monitors avoid interactions with humans.
