From the article:
"With a bill like a duck but teeth like a croc's, a swanlike neck and killer claws, a new dinosaur species uncovered by scientists looks like something Dr. Seuss could have dreamed up. It also had flippers like a penguin, and while it walked like an ostrich it could also swim.
That's the first time swimming ability has been shown for a two-legged, meat-eating dinosaur.
The tiny creature, only about 18 inches tall, roamed 75 million years ago in what is now Mongolia. Its full curled-up skeleton was found in a sandstone rock.”
