COLLEGE STATION, Texas — Scientists at Texas A&M University say a Native-American canoe found along the Red River in Louisiana is one of the largest prehistoric watercraft ever found intact in North America.

A&M said in a statement Thursday that a couple boating along the river June 7 north of Shreveport spotted a portion of the canoe jutting from a sandy bank.

Radiocarbon dating determined the canoe was made sometime in the 14th century, likely by Caddo Indians.

Scientists believe the 34-foot-long craft is a cypress that was hollowed out using hot coals and tools to char and dig out the center.

They speculate the canoe was encased in mud for some 600 years before heavy flooding last year dislodged it.

Plans call for the canoe to be returned to Louisiana for display.
