These large beasts became extinct... but why?


A Diprotodon Optatum was a heavily built marsupial. It was also the largest marsupial in the world. It became extinct after climate change and global warming impacted on it's habitat. The size of a Diprotodon Optatum is 3.8 meters long and 1.7 meters high. It was a vegetarian. It had four large main teeth for grinding vegetation. The aboriginals spears where to weak to hunt an adult Diprotodon Optatum.


It is native to Australia and lived in rainforest, marshland, savannahs and open woodland.


The Diprotodon Optatum didn't really have any shelter. It would make a make-shift-shelter. It would sleep in a cave or under a tree. It didn't make a burrow like a wombat these days.

Biological relationships

The Diprotodon Optatum was part of the competitive relationship. Nothing really hunted it. It was a herbivore and there for it didn't hunt animals.

Life cycle

The Diprotodon Optatum mated with a female then a young Diprotodon Optatum would be born. But the female would be pregnant for a few months. It grew into an adult then the life cycle will continue.

Food Chain

A Diprotodon Optatum would not be eaten by anyone but it only ate vegetation and grass. It was a primary consumer.


A Diprotodon Optatum roamed around lots of biomes like Arid desert, tree savannah, grass savannah and semiarid desert.

Interesting fact

The Diprotodon Optatum became extinct because of climate change and global warming. It was the largest marsupial to walk the face of the earth. These beasts were hervbivores.
