Ancient Kangaroo: Steel-hard jawbone that can split large trunk

More than 40,000 years ago, there was a giant kangaroo that wandered throughout western Australia. This ancient kangaroo weighs an average of 118kg, 3m high and has jaws much stronger than today's kangaroos.

The kangaroo, also known as Kangaroo , has a short face, a square skull and is a monopodate animal (modern mice have three toes). A new study shows that the jaws of giant mice have anomalous power, allowing them to chew and eat solid foods. When other food sources became scarce, ancient kangaroos were able to chew and consume hard foods like stems and twigs etc.

The shape of ancient kangaroos in Australia 40,000 years ago.

Pandas are the only contemporary animal to have the same skeletal and muscular structure as those of ancient kangaroos. Raccoons today can chew hard-bodied bamboo as well as bamboo shoots up to 15cm thick.

" In general, ancient kangaroos are quite different from modern kangaroos, with thicker bodies, long arms with more muscles and extended fingers. Usually they only have one big big toe on each. feet and head shaped like a bear "- D. Rex Mitchell, author of ancient kangaroo research said.

The kangaroo is actually just as good now!

To prove his claim, Mitchell created 3D digital models to replicate the skull and jaw muscles of ancient kangaroos.

Thereby, Mitchell discovered that the giant cheekbones of this animal is a place that contains a large amount of muscle to help the animal's jaw does not dislocate each time when performing strong bites. In addition, the bones on the front and top of the skull help form a firm arch to keep these jaw muscles from twisting.

Also according to Mitchell, ancient kangaroos have a much better adaptability than kangaroos today. Contemporary kangaroos prefer soft plants like grass, flowers, ferns, and moss. However, ancient kangaroos still suffered from extinction due to extreme climate change throughout tens of thousands of years.
