This is Africa's dinosaur¹ graveyard² - the timeless Sahara. This landscape of shifting sands has been reluctant to give up secrets hidden for hundreds of millions of years. But clues lie buried beneath.

We are on the trail of a, a number of dinosaurs³, and we begin to paint a much better picture of this time, each time we come. (I think back there)

Since paleontologist doctor Paul Sereno discovered exposed fossil fragments here in 1997, he's been meticulously⁴ planning a new assault on the Sahara. But weather, logistics, security and of course the inevitable⁵ delays need to be factored in. After negotiating these troubles, they finally make it to their remote destination. After crossing into nowhere, Paul and the team reach a site they've worked before. Bones litter this dinosaur graveyard and rarely remain hidden for long. It's part of a shoulder girdle. It's, er, distal end of a limb bone right there. We got what looks like a leg. Hey, look at this, this is a pelvis. Boy you are stepping on it.

The hunt is on. The team gathers tons of promising⁶ fossils, but otherwise life doesn't look so promising. After today, we will have a day and a half of fresh water. We are just hoping for a water truck to get here in time. There is one thing the team doesn't have to worry about running short of - fossils. Discovery after discovery, found, clustered and jacketed. And on a casual stroll one day, the biggest find - the jaw⁷ of the giant sarcosuchus, super croc.

This discovery is big, and soon Paul and the team get company - National Geographic⁸ croc expert Brady Barr(the prehistoric⁹ variety). No croc nearly that enormous lives today. The questions the discovery raised are equally enormous. What did sarcosuchus look like? What did it eat? How did it hunt? Brady and Paul realize answers lie waiting not in the sand but in the swamp, in the living descendants of the 110-million-year-old bones. The discovery behind them, the journey to understand super croc is just beginning.
