The first Thylacoleo fossil findings were discovered by Thomas Mitchell in the 1830s in the Wellington Valley of New South Wales, though not recognised as such at the time. The generic holotype, consisting of broken teeth, jaws, and a skull, was discovered by a pastoralist, William Avery, near Lake Colungolac from which the species Thylacoleo carnifex was described by Richard Owen.

Thylacoleo was a powerful carnivorous marsupial had a highly developed physique designed for strength rather than speed. Thylacoleo have a large cranium with powerful jaws, a deep chest, a short but powerful neck, and extremely muscular forelimbs. Reduced canines and incisors, massive shearing premolars that functioned as bolt-cutters, and highly specialized carnassial teeth that did the most of the killing were all present in their dentition. Their limbs include a semi-opposable thumb with a big retractable claw, cat-like retractable claws on their feet, and a powerful climbing ability that is probably scansorial. Like wombats and kangaroos, the tail is long and rigid and may be employed for tripod stability.

Thylacoleo exploits its killing abilities because it is an ambush predator that uses its forelimbs to grasp prey, has the strongest biting force per body mass of any known mammal, and has giant shearing premolars that can cut bone and hide. Large animals like enormous kangaroos or young diprotodonts could be fatally bitten by it.

Thylacoleo was able to climb trees or rugged cliffs to ambush prey, according to anatomical data (claws, shoulder structure). Thylacoleo was an ambush hunter who relied on power, surprise, and stealth rather than pursuit running. It didn't have any specific swimming adaptations, but since it was a mammal about the size of a large cat, Thylacoleo was presumably able to swim at a basic level, albeit it wasn't a strong or frequent swimmer.

In Pleistocene Australia, Thylacoleo was the top predator. They hunted by ambush, usually from rocky overhangs or trees. Giant kangaroos (Procoptodon, Sthenurus), large birds without wings, juvenile megafauna like Diprotodon, medium-sized marsupials, and recently bred dingoes are their primary prey. Quinkana (terrestrial crocodile), thylacine (less powerful), Megalania (huge monitor lizard), and humans (Aboriginal Australians) are their principal rivals and threats.

Reproduction

Like other marsupials:

• Likely gave birth to very tiny, undeveloped young

• Young would crawl into a pouch

• Pouched carnivore, possibly with 1–2 joeys at a time

• Development similar to wombats and koalas

With the exception of mating and raising young, Thylacoleo was probably solitary, territorial, ambush-oriented, and low-endurance. These marsupials may have slept in trees or caves, and trackway evidence points to methodical, cautious movement as opposed to sprinting.

If Thylacoleo had survived into the present day, it would have been a formidable, lone ambush predator with an innate tendency toward aggression or avoidance. It was similar to a wild leopard or cougar, but it was far more skilled at killing.

Coming soon

Thylacoleo was widespread in Australia's dry southern and western regions (cave sites in Nullarbor). They avoided the driest core deserts and the wettest rainforests in favor of woodlands, forest fringes, rocky places with caves (several fossil sites were found in deep caverns), and maybe semi-arid scrublands.

Even in a hypothetical scenario, Thylacoleo was highly improbable and not advised. These factors include its status as an apex carnivore, its very lethal claws and jaws, its solitary nature, its territorial tendencies, and the need for a large amount of space and a suitable diet. Thylacoleo was even more unpredictable than keeping a cougar or jaguar.
