Big Dig at New Law School Site

Workers at the construction site for the future Thomas Jefferson School of Law (Calif.) have been turning up, or better to say digging up, some amazing prehistoric finds in a half-city block location.
The latest: the bones of a giant sloth.
The fossils are the third in a succession of remains discovered at the East Village site in downtown San Diego. Kicked off in October, the $68 million project will result in a new high rise, state-of-the-art home for the law school, scheduled to be open during the 2010-2011 academic year.
On February 3, the skull, two tusks, foot and legs bones of a Columbian Mammoth, estimated to be about 500,000 years old were found, were found in the site's southeast corner according to a San Diego Union Tribune article. Just over 20 days later, the jaw, shoulder blade, neck bone and upper spine of a baleen whale dating possibly 600,000 years old, was discovered in the same spot, right above the other creature, with 10 feet of earth between them.
School officials signed a contract with a paleontological firm to be on site for the excavation, says spokesperson Chris Saunders. Workmen had to dig around the area of the two findings, but they were able to continue with minimal delay.
The school's website lists updates about the project's progression.
The latest set of bones, part of the sloth's vertebra and tooth and skull fragments, were unearthed in a different part of the property last Friday. All three animals date from the Pleistocene Period -- the Ice Age.
