It may have been one of the most cataclysmic geologic events of the last 60 million years which shaped America as we know it today. The narrow, 400-mile-long Isthmus of Panama, once buried below the sea, rose up and connected North and South America. This new land bridge unleashed an astonishing animal encounter: Prehistoric predators and prey—each unique to their worlds—came face-to-face for the first time. An armor-plated ancestor of the armadillo. A saber-toothed marsupial. A horse-like creature with three-toed feet. Evolutionary history changed forever as animals from the continents clashed.
National Geographic joins scientists on a quest to discover what happened and which creatures survived.

How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD-R Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD-R titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
