Paul Sereno, a professor at the University of Chicago and Explorer-in-Residence at the National Geographic Society, works with students, technicians and artists in his Fossil Lab to bring to life fossils unearthed from sites around the world. Sereno’s field work began in the foothills of the Andes in Argentina, where he discovered the first dinosaurs to roam the Earth some 230 million years ago. Other expeditions have explored Africa’s Sahara, Asia’s Gobi Desert, India’s Thar Desert, and remote valleys in Tibet. He also works every year closer to home excavating his own "Jurassic Park," a dinosaur graveyard in Wyoming's Bighorn Mountains. With a menagerie of spectacular dinosaurs to his credit, he also is known for discovering a series of extinct crocdilians, including the 40-foot long dinosaur-eater dubbed "SuperCroc." Sereno’s latest discovery, a human burial site in the Sahara predating the Egyptian pyramids, provides a snapshot of life in a once “green” Sahara.
