Gary Kidd had a pretty good idea that what his 3yearold grandson had found was no rock, but the tooth of a woolly mammoth (猛犸).That's because he had found one himself nine years ago.Kaleb Kidd was catching some squirrels last Monday near La Crosse when he spotted what looked like an unusual rock.
“Grandpa, what's that?” Kaleb asked.He told his grandson it looked like the tooth of the extinct (灭绝) woolly mammoth.Next stop was the Mississippi Valley Archaeology Center at the University of Wisconsin, which proved that it was, indeed, the tooth of a mammoth.
Connie Arzigian, the center's lab director, said it could be 10,000 to 30,000 years old.It weighs 2 pounds and measures 15 centimeters long and 7.6 centimeters wide.
The center already has a woolly mammoth tooth in its collection, but it's always fun to see someone discover another one. Arzigian said.“It's wonderful to get an idea of what was here in the past,” she said.
The latest find is in better shape than the one Gary Kidd brought up from the bottom of the Mississippi River while clamming (捕蛤蚧) in 1998.That_tooth was watersoaked and had fallen apart, he was told when he took it to the center.
Gary Kidd, 46, said it would be up to Kaleb' s father, Travis, to decide what to do with the tooth.For now it is on display at Satori Arts Gallery, much to Kaleb's sadness.
