SAN FRANCISCO (AP) - A crane operator has pulled a mammoth tooth during excavation for a California transit center.
Experts say the 10-inch-long brown, black and beige tooth, which was broken in two and missing a chunk, belongs to a woolly mammoth that roamed the San Francisco region some 10 million to 15 million years ago.
Paleontologist Jim Allen tells the San Francisco Chronicle (bit.ly/RO8Bhq) that the downtown find on Monday is significant.
A crane operator digging down 200 feet unearthed the tooth at the massive Transbay Transit Center construction site.
Allen says the tooth is in remarkable condition with the enamel still intact, and has not deteriorated to the point of most fossils.
