Quintaglio Ascension Series by Robert J. Sawyer

The Face of God is what every young saurian learns to call the immense, glowing object which fills the night sky on the far side of the world. Young Afsan is privileged, called to the distant Capital City to apprentice with Saleed the court astrologer. Buth when the time comes for Afsan to make his coming-of-age pilgrimage, to gaze upon the Face of God, his world is changed forever- for what he sees will test his faith... and may save his world from disaster!

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... moreFossil 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.

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. less

Now they must quickly advance from a culture equivalent to our Renaissance to the point where they can leave their planet. While the Quintaglios rush to develop space travel, the discovery of a second species of intelligent dinosaur rocks their most fundamental beliefs... moreIn Far-Seer and Fossil Hunter, we met the Quintaglios, a race of intelligent dinosaurs from Earth and learned of the threat to their very existence.
