Dinosaur tail unearthed
Buried for up to 72 million years, one of the world's largest intact dinosaur tail fossils has been uncovered by paleontologists in the northern Mexican state of Coahuila.
Paleontologists from Mexico's National Institute for Anthropology and History (INAH) and National Autonomous University of Mexico (UNAM) brushed away sand and gravel for nearly 20 days, slowly revealing a record 50 connected vertebrae on the 16-foot tail.
