Johannesburg – A two million-year-old fox fossil has been discovered at an archaeological dig at the Cradle of Humankind world heritage site in Sterkfontein, Gauteng, researchers have announced. "It's exciting to see a new fossil fox. The ancestry of foxes is perhaps the most poorly known among African carnivores and to see a potential ancestral form of living foxes is wonderful," Dr Brian Kuhn, of the University of the Witwatersrand's Institute for Human Evolution (IHE) said. In an article published in the Transactions of the Royal Society of SA, the researchers named the previously unknown species of fox Vulpes Skinneri. "We [the authors] think that John would be pleased, and it is fitting that this rare little find will carry his name forever," they wrote.
