NEW YORK Dwarf dinosaurs? Who knew?

German scientists have discovered a species of the long-lost creatures that was just one-third the size of its closest relative. Researchers think those dinosaurs underwent what's called island dwarfism. That's when big species tend to shrink over generations on an island.

They believe it roamed some 154 (m) million years ago in what's now northern Germany.

But even a dwarf dinosaur would be a force to be reckoned with, were it still around today. Scientists think it weighed about a ton, and measured some 20 feet from the snout to the tip of its tail.
