Mongol hoard

A new type of Dromeosaur has been found in Inner Mongolia. Linheraptor exquisitus is about 2.5m long, and the skeleton is not far off complete - a great find sparked by the discovery of a claw sticking out of a cliff face. A couple of PhD students made the find. Jealous.

I've been out looking for fossils plenty times in my life, and have yet to actually find something halfway decent. I've found fair examples of common things, and poor examples of rarer things, but have still not stumbled over a complete, previously undescribed dinosaur. What am I doing wrong?
