- <p>A stunning discovery provides clues to the course of evolution
- </p>
- <p> Imagine a monster with the teeth of a shark, the talons of
- an eagle, the neck of an antelope and the hindquarters of an
- ostrich. A mythological chimera? Not at all. "I stepped down
- into this gulch," recounts University of Chicago paleontologist
- Paul Sereno, "took 25 steps and screamed." Directly ahead, atop
- a sandstone knoll, lay the full skeleton of a 2-meter-long
- (about 6 ft.) carnivore. It proved to be the most ancient
- dinosaur discovered to date.
- </p>
- <p> Last week, at the meeting of the Society of Vertebrate
- Paleontologists in Austin, Sereno for the first time revealed
- details of the find, made last year by a joint U.S.-Argentine
- expedition. The dinosaur was named Herrerasaurus, after
- Victorino Herrera, the goat farmer who first led scientists to
- the area in northwestern Argentina where the bones were found.
- Smaller than Apatosaurus and less fearsome than Tyrannosaurus,
- this dinosaur flourished 230 million years ago during the unique
- period when most of the earth's landmasses were gathered into
- a single supercontinent, now called Pangea. Until the most
- recent find, only a smattering of Herrerasaurus bones had been
- unearthed. Now scientists will be able to look over the complete
- skeleton for important evolutionary clues. While Herrerasaurus
- is not the long sought common ancestor of all dinosaurs, notes
- Sereno, "it's close -- and maybe it's as close as we will ever
- get."
