By way of comparison, here's the part of the earth they were in: the people: the world in which they lived: At present it is assumed that these birds originate in Asia and were transferred to America. It was probably from America to Europe, as the main regions were nearer together than Asia and Europe. Soon after the K-Pg incident, for example, primitive but recognizable species of animal became widespread in Eurasia and North America.
Tracing rhinoceroses, tapestries and ponies through fossils, one gets an organism that was very similar to these early perissodactyls. About 50 million years ago, Eohippus was living in North America and is generally regarded as one of the first horse kin. He was living in woods where he was eating fruit and leaf in a way that is probably very similar to that of the contemporary tapir.
Simultaneously, we see a progressive alteration of the teeths of these creatures and their nearest relations, which are becoming harder and more specialised for sharpening. As a result, many livestock began to adapt to these new circumstances, and the early ponies were among them. A few were even adjusted to the forest and expanded to Asia.
Over a long period (about 15 million years) the whole wide range of different types of three toe-horses was present. The majority of them were living in North America, but many were spreading to Asia and Europe. You can see that the road to Europe now led through Asia, not North America: But the first "modern" one-toed animals were also born in North America, about 5 million years ago, but quickly expanded into the Old Testament, where they quickly became diverse into the contemporary breeds we know today: horse, donkey, ass, donkey, donkey and zebra.
As South America was linked to North America about 3 million years ago, some also extended to the south. In America, however, the horse died out about 12,000 years ago, possibly because of over-hunting by the natives of America. At any rate, the success of a horse is not nearly as good as in the past.
Artiodactylene (also toe ungulates) such as stags, swine, cows, antelopes, chamomiles, etc. dominate the globe, and while in the past there were many species of horse, we now have only one: equine. We' re accustomed to the horse because it's become priceless to us, but it's really an outlandish group.
