Researchers Say Mammoth Tusk Could Date Back to 14,000 B.C.
OSKALOOSA, Iowa (AP) — Researchers say they've found fragments of a 4-foot-long mammoth tusk at their dig on a southern Iowa farm.
The Oskaloosa Herald reports that the fragments were found Sunday at the site in rural Mahaska County.
A nearly complete mammoth skeleton was found buried there, and scientists have been gathering pollen grains, seeds and other plant material in an effort to determine what the area was like so many thousands of years ago.
Scientists say they've received the results of a radiocarbon date test on a log recently discovered at the site. Dave Brenzel, of the Indian Creek Nature Center, says the log dates back to 14,000 B.C.
