But in July 1993, Ruben Dario Carolini was doing exactly that in the badlands southwest of Villa El Chocon when he uncovered a leg bone longer than he was tall. The bones belonged to Giganotosaurus carolinii, one of the largest meat-eating dinosaurs ever found, and the discovery was so important that the town built a museum around it. The Ernesto Bachmann Paleontological Museum opened in 1997, and the giant carnivore is still the reason anyone makes the trip.

Here is Amargasaurus cazaui, a sauropod with two rows of tall spines rising like a sail from its neck, and a cast of the head of Bajadasaurus pronuspinax, whose forward-curving ne...

What it holds there is precious: holotype sp...

Carolini was a self-taught fossil hunter, not a credentialed scientist, and the largest predator of his hemisphere now bears hi...
