Archaeologists find a 10,000-year-old weapon at site of new Ontario arena

Archaeologists in Windsor, Ont., have revealed a 10,000-year-old stone weapon produced by the first humans who lived in the territory.
Newmarket archaeologist Kim Slocki said she found a single “projectile point” in her pre-construction study of the site of a new arena.
“It’s at least 10,000 years old,” Slocki said.
She said the artifact comes from Paleoindian hunters often called the “first people of Ontario.”
Other archeologists familiar with the area said her find is at least 7,000 years older than anything earlier discovered there.
Archeologist Christopher Ellis, one of North America’s leading experts on Paleoindians, portrayed them as nomadic hunters and fishermen who moved into southern Ontario as the glaciers moved away. “It’s like a needle in a haystack to find one of these sites,” said Ellis, who also teaches at the University of Western Ontario.
He also said that based on U.S. excavations, it’s believed Paleoindians hunted mastodons.
“In Ontario, they may have hunted caribou and Arctic fox, based on bones found at one site”, said Ellis
A 15-metre by 10-metre site where the artifact was found has now been fenced off for a more inclusive archeological dig in the spring, Slocki said.
