A group of raptors, called Deinonychus, kill a small armored sauropod and begin tearing it apart. They are interrupted when a Tyrannosaur shows up and steals their meal. They can't compete with it, as they are only 1/10th it's size. So they return to their nest and communicate this with the others there. Meanwhile, the satiated T-Rex goes back to its own nesting ground. The raptors soon show up and steal some of the eggs, in obvious revenge. This pisses the giant carnivores off. So begins a violent back-and-forth between the two species of predators...
I've always been impressed by this graphic novel, as everything is conveyed through the illustrations. There is no text whatsoever to accompany the panels.
The various dinosaurs, from ankylosaurs to triceratops to giant crocodilians, are given distinct personalities. Mankind's forerunner, a small marmoset-like mammal, even makes an appearance.
The book is comparable to the BBC television series, WALKING WITH DINOSAURS, as well as comics creator Steve Bissette's TYRANT series. Highly recommended.
