<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>
<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.
