New dinosaur raptor found | Science Blog:
Neuquenraptor argentinus wasnt much of a standout. It was only of average height and weight for its kind, measured six feet from head to tail, and brandished a razor-sharp claw for slashing prey.
Now, its bones provide the first uncontroversial evidence that raptors roamed the prehistoric world beyond the Northern Hemisphere 90 million years ago, said Diego Pol, a postdoctoral researcher at Ohio State. Before this, the extent of the dinosaurs range wasn't certain.
These are evolutionary hypotheses being tested, and new data on the history of life on earth being gathered.
