Carleton adjunct professor Paul Thibaudeau has unearthed over 7,000 items in a rare site of human activity near Casselman, east of Ottawa, according to the Ottawa Citizen. The items have been dated from about 3,500 to 9,000 years ago.

Member of Thibaudeau’s crew and Carleton student Kelly Berckmans found what turned out to be a crystal quartz end scraper, which sparked further archaeological interest in the site. Many of the artifacts found were made of stone from southern Ontario, western New York state, Pennsylvania and northern Quebec, which confirmed earlier discoveries that migratory people hunting and fishing in eastern Ontario participated in a vast trading network, according to the Citizen.

Thibaudeau is an adjunct research professor at Carleton, cross-appointed between the sociology and anthropology department and the School of Industrial Design, according to Carleton’s website. He also completed his bachelor’s and master’s degrees in anthropology at Carleton in the early 1990’s.
