GENERAL CEPEDA, Mexico, July 23 (UPI) -- Paleontologists say they have unearthed one of the world's largest intact dinosaur tail fossils in northern Mexico.
Researchers from Mexico's National Institute for Anthropology and History and the National Autonomous University of Mexico said more than two weeks of slowly removing sand and gravel at a dig in the Mexican state of Coahuila have uncovered a 16-foot tail with a record 50 connected vertebrae, CBS News reported Tuesday.
