Cast of a Scaphognathus crassirostris, a kind of pterosaur. On display as part of the exhibit "Pterosaurs: Flight in the Age of Dinosaurs" at the Cleveland Natural History Museum in Cleveland, Ohio, in the United States. This animal lived about 150 million years ago. This fossil was found in the Solnhofen formation in Germany. This is a cast; the fossil itself is held by the Institute of Geology and Paleontology at the University of Bonn.

A diagram of the dromaeosaurid dinosaur Pyroraptor olympius with selected fossil elements that can be reliably scaled using measurements given by Allain & Taquet (2000) to produce a realistic estimate of the taxon's size and proportions in life. This silhouette is based on the supposition of the missing elements of Pyroraptor's skeleton having fairly generalized dromaeosaurid proportions.
