Clues at Argentina site raise possibility mammal was buried with human owners about 1,500 years ago

The remains of a fox unearthed at a human burial site in Argentina dating back 1,500 years has raised the possibility the animal may have been kept as a pet, research suggests.

Experts say the remains predate the arrival of domestic dogs in Patagonia, which occurred about 700–900 years ago, with a number of clues suggesting the fox was seen as valuable, and may even have been a companion to the hunter-gatherers it lived with.
