We do not know the color of most dinosaur, because they are only known from bones. However, paleontologists have recently found the colors of a few feathered dinosaurs. The most colorful of these was probably Sinornithosaurus, which had red/brown, yellow, grey, and black feathers on various parts of the body.
It all depends on the what dinosaur it is, for some the males have big colourful crust and big spines on the back to impress females, others it's as simple as the male is larger.
peacock
All of them are colourful but after seeing pictures i would say the Mandarin fish.
Camelion
is the tyrannosaurus rex the most powerful dinosaur
Not necessarily. As trichromats, human color vision is better than most, and we're not particularly "colorful".
maratus volans(peacock spider)
more colorful, most colorful
I'd have to say tropical birds.
The province that has the most dinosaur fossils is ALBERTA
the brontosaurus wasn't a dinosaur it was a carmasaurus head on another dinosaur's body.
It depends what type of dinosaur it is, most dinosaur books have pictures of them though, but most of them looked like big lizards or monsters.
