       Caihong is a genus of anchiornithid dinosaur that lived in Asia during the late Jurassic.‭ ‬Caihong was a very small dinosaur,‭ ‬roughly about forty centimetres long in life.‭ ‬Caihong is noted for having feathers covering the entire body except for the snout and claws.‭ ‬Study of melanosome associated with Caihong show that in life Caihong probably had black iridescent feathers over most of its body,‭ ‬while the feathers of the head,‭ ‬neck,‭ ‬chest and base of the tail were brightly coloured.‭ ‬This patterning is suggested by the observation that these feathers had platelet like melanosomes denoting colours like those seen in trumpeter birds.‭ ‬This is because the platelets are solid with no air bubbles,‭ ‬like the platelet melanosomes of these birds.‭ ‬At the time of its description,‭ ‬this also means that Caihong is the earliest known appearance of platelet like melanosomes in the fossil record.
