 Goldfuss was the first to describe fur-like integument on a pterosaur, which was restored in his commissioned 1831 illustration based on his observation of the holotype specimen of "Scaphognathus".This observation, which was rejected by scientists such as Hermann von Meyer, was later vindicated with certainty by 21st-century imaging technology, such as reflectance transformation imaging, used on this specimen.The role of art in disseminating paleontological knowledge took on a new salience as dinosaur illustration advanced alongside dinosaur paleontology in the mid-1800s.
