Imagine you are planning a trip to help a paleontologist. Dinosaurs are reptiles (class: Sauropsida), part of the phylum Chordate, which in turn is part of the kingdom Animalia. Scientists do not know the exact lifespan of dinosaurs, but they estimate that they lived about 75 to 300 years. Based on the size of Quetzalcoatlus’ jaws and neck, it is possible that, were they alive today, they would be able to swallow a man whole without difficulty. Few of the specimens that are recovered are complete skeletons, and impressions of skin and other soft tissues are rare.
