Equus ferus

The equus ferus is the horse. The surviving subspecies are all dometicated and feralized variants within exception to the Prezwalski's horse, which is treated in the commoner world more like a separate species of horse (though most domesticated animals are to their wild variants, I feel it more. I was surprised to re-learn that it was a subspecies and not a species). The extinct species domesticated horses derived from is called Equus ferus ferus, and the others are Equus ferus caballus and might be given different subspecies names depending on their rewilded location as well as extinct variations from different places.https://en.wikipedia.org/w/index.php?title=Wild_horse&oldid=1179034972
It seems that the extinct wild horses of ancient Europe are sometimes called "tarpans". For some, this is a term loaded with scientific and linguistic issues.https://www.theextinctions.com/articles-1/5wa1nzaq7zveeuawomiqu2n3c6cfdj There are relatives to these horses that are also called tarpans. This would be Equus caballus.
