Overview Compsognathus is a genus of small, bipedal, carnivorous theropod dinosaur. Members of its single species Compsognathus longipes could grow to around the size of a chicken. They lived about 150 million years ago, during the Tithonian age of the late Jurassic period, in what is now Europe. Paleontologists have found two well-preserved fossils, one in Germany in the 1850s and the second in France more than a century later. Today, C. longipes is the only recognized species, although the French specimen was once thought to belong to a separate species named C. corallestris.

Why it matters Described in 1859 from the Solnhofen limestone, the same lagoons that preserved Archaeopteryx. A lizard skeleton inside its ribcage is one of the earliest known dinosaur stomach contents. Thomas Huxley used it in 1868 to argue that birds evolved from dinosaurs. Classification & discovery
