A few years back, while crashing at my apartment for the night during a long trip west, a friend of mine asked me “Haven’t paleontologists found all the dinosaurs already?” Museums from coast-to-coast seem well-stocked with primordial reptiles, and, really, when dealing with such giants, how many species could there possibly be? I had to chuckle at my friend’s question. Not only were there more dinosaur species than we ever imagined, but we’re still a long way from finding them all.

I can’t think of a place that better exemplifies the dinosaur boom than North America’s southwest. Hell, the fantastic new species coming out of the area from the four corners on south was half the reason I moved to Utah.
