AND THE WINNING ROAR BELONGS TO ...

Dinosaurs have been dead 65 million years, as any school kid worth his weight in ``Lost World'' action figures will tell you.

But that doesn't mean you can't imagine what they might have sounded like. Loud. A bit screechy. Definitely scary.

Those sounds were brought back from extinction Wednesday at a dinosaur-roaring contest held at Universal Studios Hollywood theme park.

Twenty-six students from Oxnard Street Elementary School in North Hollywood competed in the contest, which was judged by a panel of people who worked on the Steven Spielberg film: stars Vanessa Lee Chester and Alex Miranda of Sylmar; dinosaur expert Don Lessem; and sound mixers Greg Landaker, Steve Maslow and Bill Varney.

The contest was won by 10-year-old Luis Guevara. In addition to getting a backpack full of prizes, including yearlong passes to the park for his family, Guevara howled his way into ``Jurassic Park'' history. His imitation of a velociraptor will be digitally enhanced and used as a sound effect for ``Jurassic Park - The Ride.''
