A 12-foot Columbian mammoth tusk has been unearthed in Idaho and scientists say more of the fossil skeleton might still be buried at the site, the AP reports. Researchers say the large herbivore lived 72,000 to 200,000 years ago and was about 16 to 19 when it died. Its left tusk was found earlier this year at American Falls Reservoir.

"That's a really good find out there," said Mary Thompson, collections manager at the Idaho Museum of Natural History at Idaho State University. "We know we have Columbian mammoth (in the region). We're constantly finding bits and pieces." You can read a full report here from AP reporter Keith Ridler.
