Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process. However, recent studies of feathered dinosaurs and skin impressions have shown the colour of some species can be inferred through the use of melanosomes , the colour-determining pigments ...

Sinosauropteryx (meaning "Chinese reptilian wing") is a compsognathid dinosaur. Described in 1996, it was the first dinosaur taxon outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers. It was covered with a coat of very simple filament-like feathers.
There have been some discoveries of unusually well-preserved fossil dinosaur specimens which bear remnants of tissues and bodily structures.Organic tissue was previously thought to decay too quickly to enter the fossil record, unlike more mineralised bones and teeth, however, research now suggests the potential for the long-term preservation of original soft tissues over geological time, [1 ...
Ceratopsia or Ceratopia (/ ˌ s ɛr ə ˈ t ɒ p s i ə / or / ˌ s ɛr ə ˈ t oʊ p i ə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia.
Caudipteryx (meaning "tail feather") is a genus of small oviraptorosaur dinosaurs that lived in Asia during the Early Cretaceous, around 124.6 million years ago.They were feathered and extremely birdlike in their overall appearance, to the point that some paleontologists suggested it was a bird.
Borealopelta was a large dinosaur, measuring 5.5 metres (18 ft) long and weighing 1.3 metric tons (1.4 short tons). The Suncor specimen is remarkable for its three-dimensional preservation of a large, articulated dinosaur complete with soft tissue.
Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
