Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process. However, recent studies of feathered dinosaurs and skin impressions have shown the colour of some species can be inferred through the use of melanosomes , the colour-determining pigments ...

Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria."

Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur known from the Late Cretaceous Maastrichtian age of North America. The first specimen, recovered in 1971 from the Javelina Formation, consists of several wing fragments.
