According to Wang and Tedford, the first true foxes appeared in North America late in the Miocene (around 9 mya) and were represented by a small Californian species known as , which was found in the Central African country of Chad and dates to the late Miocene (some 7 mya).
Recent work by Louis de Bonis and colleagues at the Université de Poitiers in France has suggested that the foxes and other canids first spread throughout Africa, before invading Europe via a trans-Mediterranean route towards the end of the Miocene.
Briefly, the creature that taxonomists currently think gave rise to modern-day dogs was a medium-sized (about the size of a coyote) grassland predator of North America called that appeared during the late Eocene, some 36 mya.
The caniforms subsequently diverged into three lineages (which we call subfamilies): the Hesperocyoninae (‘western dogs’); the Borophaginae (‘bone-crushing dogs’); and the only one still around, the Caninae, which includes the dogs, wolves, foxes, etc.
Whenever and wherever this species first appeared, fossil evidence suggests that the modern Red fox has been in North Africa for the last 700,000 years and Europe for at least the last 400,000 years.
In Britain, remains of the Red fox have been found in Wolstonian Glacial sediments from Warwickshire, suggesting that they were around between 330,000 and 135,000 years ago.
