A “lost world” of early dinosaurs roamed the Antarctic long after they were supplanted in the rest of the world, the recent discovery of fossilized bones suggests.
A team of dinosaur-hunters has found remains of a new species which dates from only 70 million years ago, but which bears striking similarities to dinosaurs thought to have died out everywhere else ten of millions of years earlier.
Expedition leader Judd Case, dean of science and biology professor at California's Saint Mary's College, told globeandmail.com from Washington, D.C., that the radically changing day-night cycle of the far south probably slowed the spread of flowering plants, which could in turn have limited the evolution of the massive, plant-eating dinosaurs found farther north.
