High-tech dig for a dinosaur

The use of remote sensing to uncover the skeleton of the seismosaurus, a dinosaur at least 37 meters long, is discussed. Most of the seismosaurus skeleton is believed to lie under 3 to 5 m of sandstone, in a government preserve, so the dig must disturb the environment as little as possible. The techniques being used are radar, magnetometry, gamma rays and acoustic tomography.<
