EDINBURGH, Ind. (AP) - A large oak tree dug up last summer in a southern Indiana gravel pit is about 2,000 years old — far younger than scientists' preliminary estimate. Scientists who examined the log last year initially speculated it could be 6,000 years old.
However, radiocarbon testing that measures the radioactive decay of carbon in materials determined that the oak log is about 2,000 years old, said Anthony Swinehart, an associate professor of biology at Hillsdale College in Michigan.
"It isn't quite what we thought, but from a scientific standpoint it is still good news," he said.
