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 ...
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 ...
Borealopelta (meaning "Northern shield") is a genus of nodosaurid ankylosaur from the Lower Cretaceous of what is today Alberta, Canada.It contains a single species, B. markmitchelli, named in 2017 by Caleb Brown and colleagues from a well-preserved specimen known as the Suncor nodosaur.
The fossil did not have skin from the dinosaur's feathered regions, but the researchers think these areas had bird-like skin. "This discovery adds nuance to our understanding of feather evolution.
Furthermore, bones include a number of elements formed in the skin such as gastralia, bony scutes, and spikes. [21] Paleontologists most frequently study the morphology of bones, but also their histology (the inner microstructure up to the cellular level) and chemical composition provided important insights into dinosaur biology.

The mummy in bottom view, with outline drawing. AMNH 5060 is considered one of the best preserved dinosaur fossils ever discovered. [11] The scientific value of the mummy lies in its exceptionally high degree of preservation, the articulation of the bones in their original anatomical position, and the extensive skin impressions enveloping the specimen.
The Edmontosaurus mummy SMF R 4036 is an exceptionally well-preserved dinosaur fossil in the collection of the Naturmuseum Senckenberg (SM) in Frankfurt am Main, Germany. Found in 1910 in Wyoming, United States, it is ascribed to the species Edmontosaurus annectens (originally Trachodon), a member of the Hadrosauridae ("duckbilled
A row of small osteoderms (skin bones) was present down the middle of the neck, back, and tail. Additional osteoderms were present at unknown positions on the animal's body. Ceratosaurus gives its name to Ceratosauria, a clade of theropod dinosaurs that diverged early on from the evolutionary lineage leading to modern birds.
