- <p>A dog-size carnivore may have been a founding father of the
- dinosaur clan
- </p>
- <p> Forget about whether an errant comet, angry volcano or
- invidious virus killed the dinosaurs 65 million years ago.
- Scientists have still not explained how the Saurian dynasty got
- started or why it dominated the earth for more than 150 million
- years. The discovery in northwestern Argentina of the fossilized
- skeleton of a 10-kg (22-lb.) carnivore that is 230 million years
- old may help paleontologists begin to solve the mystery. In the
- British journal Nature, researchers from the University of
- Chicago and the National University of San Juan, Argentina,
- report that the dog-size predator is the most primitive dinosaur
- ever found.

- <p> Although the ancient hunter lacked the flexible lower jaw
- and other advanced features of its more ferocious descendants,
- the overall shape and internal structure of its bones provide
- strong evidence that the beast was a true dinosaur. "This fossil
- confirms our suspicions that dinosaurs began as small,
- carnivorous, bipedal animals," says Paul Sereno, an assistant
- professor of anatomy at Chicago and a leader of the expedition.
- "We are just a couple of steps away from the ancestor of all
- dinosaurs." The scientists named the find Eoraptor, or "dawn
- stealer," because it appeared at the dawn of the dinosaurs and,
- considering its modest size, probably used stealth rather than
- brute force to snatch small prey.
