Compsognathidae is a family of small carnivorous dinosaurs, generally conservative in form, from the Jurassic and Cretaceous Periods. Compsognathids lie at or near the origin of feathers--skin impressions are known from three genera, Sinosauropteryx, Sinocalliopteryx, and Juravenator. While Sinosauropteryx and Sinocalliopteryx show evidence of a full covering of simple, primitive feathers, Juravenator shows evidence of scales on the tail and hind legs. It is possible that feathers arose within this family, and/or that some species were only partially feathered.

| - Compsognathidae is a family of small carnivorous dinosaurs, generally conservative in form, from the Jurassic and Cretaceous Periods. Compsognathids lie at or near the origin of feathers--skin impressions are known from three genera, Sinosauropteryx, Sinocalliopteryx, and Juravenator. While Sinosauropteryx and Sinocalliopteryx show evidence of a full covering of simple, primitive feathers, Juravenator shows evidence of scales on the tail and hind legs. It is possible that feathers arose within this family, and/or that some species were only partially feathered. The position of the Compsognathidae within the Coelurosaur group is uncertain; some hold the family as the basalmost of the coelurosaurs, while others as part of the Maniraptora.
