modern kangaroo was a giant ancestors
Remember, the article we wrote about that all existing animals are the smaller copies of the prehistoric giants. Kangaroos that inhabit modern Australia, are no exception and they too have ancient ancestors, the body weight of which exceeded 200 kg. Recently, Australian scientists have created a computer model of the skull of one of the ancestors of modern kangaroos and found out what they ate and who else from modern animals were similar.
The Interest of scientists called the skull of an ancient kangaroo Simosthenurus occidentalis species that became extinct about 42 thousand years ago. Modern marsupial inhabitants of Australia, on average, weigh about 90 pounds, but the body weight of their ancient kinsman was about 118 pounds. From encyclopedias and documentaries from childhood, we all know that kangaroos have an elongated face. However, thousands of years ago the muzzle of their ancestors was relatively short, and the jaw is allowed to chew solid foods like Mature leaves and branches.
Skull kangaroo species Simosthenurus occidentalis
Creating a computer model of the skull of the ancient kangaroos, the researchers came to the conclusion that is so strong jaw today have only pandas and koalas. on the top of the skull formed arch which gave strong muscles of the jaw to curl. Muscles, in turn, protect the jaw from dislocation during chewing of solid food.
Reconstruction of an extinct species of kangaroos.
According to the researchers, the ancient marsupials had developed a powerful jaw and began to eat solid food in order to survive. The fact is that throughout history, many animals had to literally fight for food, because of its lack. While everyone else fought over the soft vegetation, the kangaroo was able to eat solid leaves and rough twigs, which was interesting to nobody. Over time, the shortage of food is gone, so are their descendants today have got elongated snouts and feed on grasses, flowers and moss.
However, some scientists do not want to call the modern kangaroos are the direct descendants of Simosthenurus occidentalis. More in common with the ancient giants have a tiny marsupial mammals known as striped Wallaby-hare. Today they inhabit only two Islands of the Western coast of Australia . They look like shown in the video below.
It is Worth noting that recreated on the computer ancient kangaroo is the largest of its kind. Millions of years ago in Australia lived and larger members of the genus kangaroo. Take, for example, the kind of Procoptodon goliah, some specimens of which weighed more than 244 pounds. After this fact, probably no one was left in doubt that in prehistoric times on our planet lived the real giants.

If doubt still exists, personally I recommend you to read our that lived about 20 million years ago in the Miocene epoch. The growth of these birds was about 1 meter and the weight has reached 7 kg.
