Australosphenida facts for kids
Australophenida are a very old group of mammals that have mostly disappeared over time. Think of them as ancient relatives of today's mammals! Today, you can only find living members of this group in Australia and New Guinea. There are only five species left, but scientists have found fossils of their ancestors in places like Madagascar and Argentina, showing they used to live in many more parts of the world.
The two main types of animals still alive in this group are the amazing platypus and the spiky echidnas.

What are Australophenida?
Australophenida is a scientific term for a special group, or clade, of mammals. These animals are unique because they are monotremes. This means they are mammals that lay eggs instead of giving birth to live young, which is very rare! Most of the animals in this group are now extinct, meaning they no longer exist.
Where do they live?
Today, the few remaining Australophenida species live only in Australia and New Guinea. These places are like their last strongholds. However, fossils found in other parts of the world, like Madagascar and Argentina, tell us that millions of years ago, their relatives lived across different continents. This shows how much the Earth and its animals have changed over time.
Meet the Survivors
Only five species of Australophenida are still alive today. They are all part of a group called Monotremata. Let's meet them:
The Platypus Family
- Ornithorhynchidae: This family includes the famous platypus.
- Obdurodon: This was an ancient relative of the platypus that is now extinct.
The Echidna Family
- Tachyglossidae: This family includes all the different types of echidnas, also known as spiny anteaters.
Extinct Relatives
Scientists have also found fossils of other Australophenida that are no longer with us:
- Kollikodontidae: These were ancient, extinct relatives.
- Kollikodon: An example of an extinct species in this family.
- Steropodontidae: Another family of extinct Australophenida.
- Steropodon: An extinct species from this group.
- Teinolophos: Another extinct species, giving us clues about early monotremes.
