A Lost World Discovered:
Final Dinosaur Summary by Paul Sereno and Gabrielle Lyon


Brushing the knee joint, Paul is dwarfed by
the enormous hind limb of Jobaria.

The place: Outer Mongolia's Gobi Desert. The Year: 1922 No one had ever seen a dinosaur egg nest before. The oval textured eggs were beautifully preserved in the red-colored sand that covered them 80 million years ago. Within a foot of the nest lay the skeleton of a strange two-legged raptor with long, recurved hand claws.

Roy Chapman Andrews and his crew from New York set out to explore Central Asia's great desert in hopes of finding the origin of man. Instead, his team discovered a lost world of Cretaceous dinosaurs, dinosaur egg nests and tiny dinosaur-age mammals. The expedition, which generated wide public interest even then - is now legendary.


Hundreds of people were awed by the skeleton during
the Flamme de la Paix celebration.

Are there any places left in today's small world where one can explore with the chance of discovering animals so new to science that they shed light on the deep history of an entire continent? How many chances does any team have to unearth a lost world?

We set out to Africa's Sahara desert with ambitious dreams of exploration - and four months to make them a reality. We planned to visit three time horizons - Cretaceous rocks dating back 135 million, 110 million and 90 million years - all located in the parched upper half of the Republic of Niger.


One of the highlights of Camp 2 was the discovery of the most complete jaw so far of the new, large predator. Here, Paul brushes away 110-million year old rock while a herd of camels passes by on the horizon.

A week ago we were in the field, sleeping on cots, hunching in sleeping bags against the cold of the desert night as we watched showers of shooting stars, visiting the guards to joke with them by their fire, pounding rock and mixing plaster, walking with long strides across flat plains and rocky outcrop keeping eyes on the ground in the hopes of spotting a fossil.

After collecting 20 tons of fossils, mixing 100 bags of plaster, building 274 jackets, repairing 21 flat tires, the 2000 Expedition to Niger is over.


Every morning at about 6:45AM, Paul tells the team about plans for the day, the next week and general announcements.
