To which mammalian order did Thylacoleo carnifex belong taxonomically?
Answer
Diprotodontia
Thylacoleo carnifex was fundamentally a marsupial, placing it within the mammalian order Diprotodontia. This order encompasses the majority of Australia's native herbivores and omnivores, although Thylacoleo was a specialized predator within that group. This classification distinctly separates it from placental mammals, such as true cats, which belong to the order Carnivora. Its biological relationship is significantly closer to modern animals like the wombat than to any extant feline species, highlighting that its superficial resemblance to a cat is due to evolutionary pressures rather than shared direct ancestry within the placental group.
