Discovery Rocks Scientific Community.

The scientific community was rocked today when two professors from the University of Argentina announced the discovery of a new species of dinosaur resembling a monkey. The newly discovered species, which lived 125 million years ago in what is now Argentina, could re-write the textbooks on dinosaur evolution, perhaps on evolution itself.

The creature "stood" three feet tall with the body structure of a monkey, the head of a velociraptor, and the grasping "hands" and feet of modern tree-climbing lizards.

It "really shouldn't be a surprise," said an expert not involved in the discovery, Thomas R. Paine Jr. of the University of Arizona.

"The fossil record really is sparse. We have only scratched the surface of what is to be known about dinosaurs. The fact that this dinosaur resembles a monkey shouldn't be a surprise at all. Nature re-uses similar designs again and again. We have found dinosaurs that resemble Rhinos and Dolphins so why not monkeys?"

The species appears to be a relative of the Velociraptor, made famous in the movie Jurassic Park.
