Unexpected discovery

The Raptorex specimen was illegally dug out of from a fossil field in northeast China in the last decade, University of Chicago paleontologist Sereno said, and sold into an illegal international black market for fossils. Seven years ago, Henry Kriegstein, a Massachusetts eye surgeon with an abiding love of dinosaurs, attended an Arizona fossil show where a dealer showed him photos of the fossil, still in the block of rock as it was when pulled out of the ground. It was for sale, legally according to present U.S. laws, and Kriegstein said he bought it for “tens of thousands of dollars, but well below $100,000." Three years ago, after he began learning that it was possibly an extraordinarily important fossil, he decided to ask the widely-respected Sereno, whom he deeply respects, to write the first scientific article on it, introducing it to the scientific record.
