Has anyone here besides me read Dinosaur Wars and Dinosaur Wars: Counterattack by Thomas P. Hopp?
The books are full of action and suspense, and they really surprise you many times. Interesting theories that contradict our own are introduced in the books, explained so well they are believable.
If anyone is interested, here's the premise of the books:
A group of astronauts reactivates something on the moon, and not long after, communications and weaponry are being destroyed, and dinosaurs are reappearing. The earth is being invaded by the Kra, an ancient race of intelligent human-sized dinosaurs, poised to reclaim the planet and turn humans into a food source. And humanity's only chance of survival is a small group of military forces, NORAD, a pair of scientists, and a trio of humans and their Kra friend, Gar, who wants peace.
