An expedition led by paleontologist Fernando Novas uncovered four enormous vertebrae from the giant plant-eating dinosaur Puertasaurus reuili.
The species is named for two members of the research team, Pablo Puerta and Santiago Reuil, who found and prepared the fossils for research.
Because of its size and weight, Puertasaurus's dorsal vertebra presented transport problems. The bone was divided into three pieces along its natural breaks, wrapped in plaster, and pushed through a narrow valley to a truck. They arrived at the museum of natural sciences in Buenos Aires intact and undamaged.
