Vombatiformes
Suborder of marsupials including koalas, wombats, and extinct giants.
Vombatiformes is one of the three suborders of the large marsupial order Diprotodontia. Seven of the nine known families within this suborder are extinct; only the families Phascolarctidae, with the koala, and Vombatidae, with three extant species of wombat, survive. Among the extinct families are the Diprotodontidae, which includes the largest marsupials ever, including the rhinoceros-sized Diprotodon, as well as the 'marsupial lions' Thylacoleonidae and 'marsupial tapirs' Palorchestidae.

Lore & Background
The Vombatiformes suborder comprises a diverse array of marsupials, with only two surviving families: Phascolarctidae (koalas) and Vombatidae (wombats). The extinct families include the Diprotodontidae, which contained the largest marsupials ever known, such as the rhinoceros-sized Diprotodon. Other notable extinct groups are the Thylacoleonidae, often called 'marsupial lions,' and the Palorchestidae, referred to as 'marsupial tapirs.'
Reader's Guide
The Vombatiformes suborder is significant for illustrating the evolutionary diversity of Australian marsupials. While only koalas and wombats survive today, the extinct families demonstrate a wide range of body sizes and ecological roles, from the massive herbivorous Diprotodon to the carnivorous marsupial lions. The classification within Vombatiformes includes infraorders Phascolarctomorphia (koalas and their extinct relatives) and Vombatomorphia (wombats and related extinct forms), as well as superfamilies such as Vombatoidea and Diprotodontoidea. The fossil record of this suborder helps paleontologists understand marsupial evolution and extinction patterns in Australia. The legacy of Vombatiformes is preserved in the living koala and wombat species, which are iconic representatives of Australia's unique fauna.

Frequently Asked Questions
Who is Vombatiformes?
Vombatiformes is a suborder nested inside the marsupial order Diprotodontia, uniting the koala, the three living wombat species, and seven families that have since vanished. It is one of the three major suborders recognized within Diprotodontia.
What are Vombatiformes's powers or role?
This suborder is famous for producing the most extreme body sizes ever seen in marsupials, from rhinoceros-scale herbivores to the apex-predator Thylacoleonidae. It also includes the Palorchestidae, often called the 'marsupial tapirs,' showing just how varied its members were.
How does Vombatiformes's story end?
Seven of the nine families that once made up the suborder have gone completely extinct, leaving only Phascolarctidae (the koala) and Vombatidae (the wombat) as living representatives. The rest, including the giants and the marsupial lions, survive solely as fossils.
Why is Vombatiformes important?
It holds the record for the largest marsupials ever to live and displays a remarkable spread of ecological niches, from small tree-dwelling koalas to massive ground herbivores and top predators. Its heavy extinction history also makes it a central case study in how Australia's marsupial fauna shifted over millions of years.
What is Vombatiformes's biggest member?
That title goes to Diprotodon, a member of the now-extinct Diprotodontidae family that grew to roughly the size of a rhinoceros. It remains the largest known marsupial in the entire fossil record.
