Cinco veces, la Tierra se ha enfrentado a acontecimientos apocalípticos que arrasaron con casi toda la vida de la faz del planeta. ¿Cómo eran estas criaturas prehistóricas? ¿Qué catástrofes provocaron su desaparición? ¿Y cómo sobrevivieron nuestros ancestros lejanos y dieron origen al mundo que conocemos hoy?

The Ark of the Covenant and Noah's Ark are two very different Bible stories with one burning question.

The ocean's predators use their remarkable weapons and skills to hunt or defend themselves against other hungry predators.

In a race against developers in the Rocky Mountains, paleontologists uncover a unique fossil site packed with astonishingly well-preserved bones of mammoths, mastodons, and other giant extinct beasts. The discovery opens a highly focused window on the vanished world of the Ice Age in North America.

Hace unos cien millones de años, los cocodrilos eran los T. rexes gobernantes de las aguas. Galoparon por tierra, emboscaron presas en la orilla del río, incluso aterrorizaron a los dinosaurios. Estos veloces depredadores evolucionaron a lo largo de los siglos hasta convertirse en los cocodrilos modernos que conocemos hoy. Ahora, armado con huesos de cocodrilo prehistóricos recién descubiertos, el Dr. Paul Sereno está decidido a dar vida a las antiguas criaturas y contar su fantástica historia no contada. Aprende sobre un cocodrilo que perseguía a sus presas por tierra, un supercocodrilo que apretaba sus mandíbulas alrededor de los dinosaurios, incluso un cocodrilo con una cara sorprendentemente canina. Combinando arte, ciencia forense y biología, un equipo reanima un mundo perdido de extraños cocodrilos del Cretácico que la paleontología olvidó.

While dinosaurs may have been some of the mightiest creatures ever to have walked the earth, they also could have been among the most bizarre. With extreme, exaggerated body parts, some predators were loaded with outlandish or disproportionately sized appendages. Join world-renowned paleontologists and travel the globe to unearth some of the lesser-known but most surprising members of the dinosaur family: Mamenchisaurus, whose neck alone was longer than the rest of its body; Chasmosaurus, adorned with a fashionable crown of frilly spikes to attract the eyes of potential suitors; Spinosaurus, with massive extensions from its vertebrae that could have supported a sail or a hump; and Parasaurolophus, whose tube-like head crest may look odd to us, but was a mating magnet back in the day.

At the bottom of South America, where the Atlantic and Pacific Oceans collide, is Patagonia, one of the last great wild Edens on Earth. Join National Geographic on a journey to this breathtaking subantarctic region and its crowned jewel—Tierra del Fuego—a beautifully desolate island at its most southern tip. Home to Magellanic penguins, elephant seals, right whales, and guanacos, this stark, wind-whipped wilderness now faces its greatest challenge: recovering from the misguided actions of man. With stunning footage and behind-the-scenes interviews with some of the world's most committed conservationists, Eden at the End of the World offers a wondrous glimpse into the pristine haven that is Patagonia.

En las aguas profundas del Golfo de California, en México, se congregan grandes grandes y voraces depredadores, y los pescadores locales les temen más que a los tiburones.

National Geographic embarks on a 250-mile adventure through unspoiled territory along the coast of British Columbia called the Great Bear Rain Forest. It is here that bear-hunting wolves take to the sea, grizzlies clash in titanic battles, and wild salmon are the pulsing lifeblood of an entire ecosystem. As this precious habitat faces an uncertain future, threatened by chainsaws and fish farms, a team of dedicated scientists is racing to prove that it must be protected. Forming a wilderness detective squad, these experts are searching for the rare white spirit bear and collecting clues that will decipher the secret life of the forest's elusive inhabitants.

Few creatures are as mysterious and captivating as the whale, and few connect with us so emotionally and spiritually. After hunting whales for generations, we have brought their widespread slaughter to an end, but these graceful giants still face threats on a number of fronts, and the battle to save them goes on. This film takes an intimate look at four types of whales: pilots, humpbacks, bowheads and orcas, through the eyes of the humans who are closest to them. From the struggle to save a pod of pilot whales in the Florida Keys to the groundbreaking work of a scientist risking life and limb in the Arctic to the controversy over military sonar, you'll go to the front lines of whale conservation.

Reconstitution of the alleged true story about demonic possession that was behind William Friedkin's The Exorcist.

In an age of science, one tale of the supernatural continues to seduce us: the legend of the vampire. At last, scientists are digging vampires out of their tombs to take a good, long look at them. What they're finding is a surprising factual side to the ancient legend. Fact may be stranger than fiction!
