Paleo Profile: Mexico’s Mystery Dinosaur

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.
