How is it that dinosaurs managed to survive and even thrive in the gloom of the dark and frigid polar regions? It is one of paleontology's most intriguing enigmas; but now, a unique field expedition covered exclusively by NOVA will set out for Alaska's North Slope to defrost a jackpot of new fossil clues.With the help of stunning CGI, experts will breathe life into the polar dinosaurs' lives and environment in vivid detail. The team of researchers will combine extreme engineering and perilous fossil hunting-digging a tunnel into the permafrost in order to collect the dinosaur bones-and with Alaska's spectacular wilderness as a backdrop, Arctic Dinosaurs will reveal a prehistoric lost world for the first time.Special DVD features include: materials and activities for educators; a link to the NOVA Web site; scene selections; closed captions; and described video for the visually impaired.
