Compsognathus komp-SOꞬNUHTHUHS

Compsognathus (; Greek kompsos/κομψός; “elegant”, “refined” or “dainty”, and gnathos/γνάθος; “jaw”) 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.

Many presentations still describe Compsognathus as “chicken-sized” dinosaurs because of the size of the German specimen, which is now believed to be a juvenile.
