Five ancient crocs, including one with teeth like boar tusks and another with a snout like a ducks bill, surface in the Sahara. The five fossil crocs, nicknamed BoarCroc, RatCroc, Pancake Croc, DuckCroc and DogCroc (three of them newly named species), are the bizarre remains of creatures that inhabited the southern land mass known as Gondwana some 100 million years ago, swimming and galloping across present-day Niger and Morocco when broad rivers coursed over lush plains and dinosaurs ruled. National Geographic Explorer-in-Residence Paul Sereno and his team unearth the strange crocs in a series of expeditions beginning in 2000 in the Sahara. Many of the fossils are found lying on the surface of a remote, windswept stretch of rock and dunes.
