Compsognathidae is a family of small carnivorous dinosaurs, generally conservative in form, from the Jurassic and Cretaceous Periods. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers Saurischia (sɔːˈrɪskiə, from the Greek sauros ( σαυρος) meaning 'lizard' and ischion ( ισχιον) meaning 'hip joint' Theropods (ˈθɪərəpɒd theropoda /θiːˈrɒpədə/ 'beast feet' are a group of Bipedal Saurischian Dinosaurs Although they were primarily For the prehistoric gliding reptile see Coelurosauravus.

Sinosauropteryx (meaning "Chinese lizard-wing" is the first and most primitive Genus of Dinosaur found with the fossilized impressions of Sinocalliopteryx (meaning 'Chinese beautiful feather' is a Genus of Compsognathid Dinosaur from the Lower Cretaceous Yixian Juravenator is a Genus of small (70 cm long Coelurosaurian Dinosaur, which lived in the area which would someday become the Jura 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,[1] while others as part of the Maniraptora. For the prehistoric gliding reptile see Coelurosauravus. Coelurosauria (sɨˌljʊərəˈsɔriə is defined as the clade containing all Theropod Maniraptora ("hand snatchers" is a Clade of Coelurosaurian Dinosaurs which includes the Birds and the dinosaurs that were more closely [2][3]
Taxonomic issues
In 2003, O. W. M. Rauhut redefined the family Coeluridae to include Coelurus (Late Jurassic, North America), Compsognathus (Late Jurassic, Europe), Sinosauropteryx (Early Cretaceous, Asia) and an unnamed Compsognathus-like form (Early Cretaceous, South America; this dinosaur has since been placed in the new genus Mirischia). Coeluridae is an historically Paraphyletic (unnaturally grouped family of generally small carnivorous Dinosaurs from the late Jurassic Coelurus (ˌsɨˈljʊərəs see-LOOR-us is a Genus of Coelurosaur Dinosaur from the Late Jurassic Period ( Kimmeridgian The Late Jurassic (or Malm) Epoch of the Jurassic Period is the unit of geologic time from 161 Compsognathus ( Greek kompsos/κομψος; "elegant" "refined" or "dainty" and gnathos/γναθος; "jaw" Sinosauropteryx (meaning "Chinese lizard-wing" is the first and most primitive Genus of Dinosaur found with the fossilized impressions of The Early Cretaceous ( timestratigraphic name or the Lower Cretaceous ( logstratigraphic name is the earlier of the two major divisions of the Cretaceous Compsognathus ( Greek kompsos/κομψος; "elegant" "refined" or "dainty" and gnathos/γναθος; "jaw" Mirischia is a small (two Meter -long Extinct Genus of Compsognathid Dinosaur from the Albian stage (Early However, this taxonomy has not been widely adopted. Sereno (2005) points out that Compsognathidae has priority of name, even if dinosaurs such as Coelurus or Ornitholestes belongs in the same family as Compsognathus.
