As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

In 1990, Peter Larson, with his team of commercial fossil hunters from the Black Hills Institute, discovered the most complete Tyrannosaurus Rex specimen in history. He dubbed it "Sue" after the field paleontologist who first saw it sticking out of a sandstone cliff on the ranch of Maurice Williams, a Cheyenne River Sioux Tribe member in South Dakota's badlands. Because the skelton was 90% complete, its study promised to yield up priceless information on the life and habits of the T Rex.

Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.
