Fossils have fascinated humans for centuries. From the smallest diatoms to the largest dinosaurs, finding a fossil is an exciting and rewarding experience. But where did they come from, and how long have they been around? These and many other questions are answered in this remarkable book.

A human fossil on Mars. An astronaut who lost her memory and a powerful organization that keeps a secret in Antarctica-one that will change the world forever. In 2018, Canadian archaeologist Ron Jackson makes a mind-boggling discovery in Antarctica-right before disappearing without a trace, leaving behind only his controversial theory that humans have lived on Earth far, far longer than we think they have. Decades later, in 2042, when Jackson's wife dies under mysterious circumstances, an unlikely pair of investigators, Agatha Devenworth and Pano Hofer, begin investigating whether her death might be connected to Jackson's disappearance. What exactly was it he found before he vanished? Why is the Human Foundation, a hyper-powerful business empire built on an endless series of game-changing inventions it has been rolling out, one after another, for over twenty years, trying to hide the truth from the two investigators? And what could it possibly have to do with the first manned mission to Mars, which ended in disaster leaving countless conspiracy theories in its wake?

Fossil Hunter is hard SF in the tradition of Larry Niven about a world inhabited by the Quintaglios, a dinosaurian species that has evolved a human level of intelligence and culture. Toroca, a Quintaglio geologist, is under attack for his controversial new theory of evolution. But the origins of his people turn out to be more complex than even he imagined, for he soon discovers the wreckage of an ancient starship -- a relic of the aliens who transplanted Earth's dinosaurs to this solar system. Now, Toroca must convince Emperor Dybo that evolution is true; otherwise, the territorial violence the Quintaglios inherited from their tyrannosaur ancestors will destroy the last survivors of Earth's prehistoric past.
