A trio of dogs buried at two ancient human sites in Illinois lived around 10,000 years ago, making them theĀ oldest known domesticated canines in the Americas.
Radiocarbon dating of the dogsā bones shows they were 1,500 years older than thought, zooarchaeologist Angela Perri said April 13 at the annual meeting of the Society for American Archaeology. The previous age estimate was based on a radiocarbon analysis of burned wood found in one of the animalsā graves.

An absence of stone tool incisions on the three ancient dogsā skeletons indicates that they were not killed by people, but died of natural causes before being buried, Perri said. Some researchers have proposed that whoever made the first excursions into the Americas arrived on dog-powered sleds.

Genetic evidence has suggested a second human migration from Asia to North America occurred around 11,500 years ago, with people trekking south through an ice-free corridor into the northern Great Plains. Those people likely brought dogs to the Americas, Perri proposed.
