A Lost World: Two Previously Unknown Dinosaurs Discovered in Antarctica

Arlington, Va.-- The National Science Foundation (NSF) invites members of the news media to hear about the discoveries of fossils of two dinosaurs believed to be new to science. Against incredible odds, researchers working in separate sites, thousands of miles apart in Antarctica recently found what they believe are the fossilized remains of an early plant-eating dinosaur and a meat-eater related to Tyrannosaurus Rex.

Of the two finds-which were made less than a week apart-the plant- eating beast would have lived many millions of years before the carnivore ever existed.

NSF-funded scientists from universities in California, South Dakota, and Illinois, whose research was supported by the U.S. Antarctic Program, will describe the highly unusual circumstances involved in making their finds and the significance of the finds to other dinosaur research.

NSF is an independent federal agency that supports fundamental research and education across all fields of science and engineering, with an annual budget of nearly $6 billion. NSF manages the U.S. Antarctic Program, which coordinates almost all U.S. research on the southernmost continent and in the surrounding oceans.

The event was originally webcast. The archived webcast is available at .
