"Azhdarchids are gigantic but very flying reptiles. This family of pterosaurs contains the largest known flying animals of all time, including Quetzalcoatlus, which had a wingspan of up to 40 feet and could stand as tall as a modern-day giraffe. The authors of the latest study determined that the bone represents a pterosaur from the family called Azhdarchidae. The incomplete vertebra bone, described in a journal article published in The Magazine of the Argentine Museum of Natural Sciences, was discovered in rocks from a geological formation that dates back to between 100 million and 90 million years ago. Researchers found a single neck vertebra bone on the banks of the Ezequiel Ramos Mexía Reservoir-a huge man-made lake located along Rio Negro's border with the neighboring province of Neuquén.
