Rhinoceros, Unicorns do they have mythological link?

I was fascinated with all the interesting stories I have read about the mythology and rhinoceros's . There was a fossil found by the Greeks over thousand years ago, this fossil was a fossilized thigh bone of a giant mammal. If this giant horned rhinoceros roamed Asia and Europe, there may of been other, unicorn creatures and animals that also roamed the earth. There are stories of other single horned creatures in the mythological history. The horse unicorn may of been another breed of single horned creatures. The word unicorn comes from the Latin "one-horned"

Just like rhinoceros, I believe that horsed unicorns had their horns harvested and they died out. Leaving rhinoceros's which over time got a lot smaller, maybe to try and protect them self's from poachers.

Apparently the fossils found, tells us that a breed of rhinoceros could be anything up to twelve to fourteen feet long, weighing two to three tons. That's huge! They possibly roamed the earth with the other giants of their time like the woolly mammoth. Although this particular fossil found is about a million years old, radiocarbon dating suggests the species survived until, well as late as 8000 BCE. Although they only remained in isolated western reaches of Siberia.

The rhinoceros's of today still unfortunately get hunted by poachers illegally of course, for there beautiful horn. Their horns are made of keratin, this is the same type of protein that's in hair and fingernails. The African species and the Sumatran rhinoceros have two horns while the Indian and Javan rhinoceros have just a single horn. It's also is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae. Rhinoceros fossils are identified by the characteristics of their teeth.

The superfamily Rhinocerotoidea, which includes the modern rhinoceroses, can be traced back to as early, as Eocene about 50 million years ago. With early precursors such as Hyrachyus. Rhinocerotoidea contains three families; the Rhinocerotidae ("true rhinoceroses"), Amynodontidae and the Hyracodontidae. The diversity within the rhinoceros group was much larger through out their history and they ranged from dog-sized to the size of Paraceratherium. These fantastic creatures have been around so long, but their horns is still believed to contain properties of medicine.

("People grind up the horns and then consume them believing the dust has therapeutic properties") this statement came from;

Rhinoceros are absolutely not mythological and you can clearly see evidence of their existence. There may be links to creatures part rhinoceros, in myths, but they have been on this earth a very long time. If only they could talk.

in the isolated western reaches of Siberia.
