DevotedSkeptic writes with this excerpt pulled from the San Francisco Chronicle:"A seemingly ordinary day at the Transbay Transit Center construction site became a mammoth day of discovery Monday when a mild-mannered crane operator reached deep into the earth and pulled out a tooth. This was no ordinary tooth. The 10-inch-long brown, black and beige chomper, broken in two and missing a chunk, once belonged to a woolly mammoth, an elephantine creature that roamed the grassy valley that's now San Francisco Bay 10 to 15 thousand years ago in the Pleistocene epoch."
