Were there dinosaurs that had feathers?
Even though the first dinosaurs are thought to have emerged some 245 million years ago, dinosaurs with feathers have been dated to only 180 million years ago. Yet, the story does not end there. Feathers, it seems, did not originate with the dinosaurs. According to a recent study, they may have evolved in another group.

What did feathers do for dinosaurs?
At least one dinosaur apparently used its feathers for defence, and this may have been a viable strategy for other. Still bristles on the animal may have made them harder to attack or eat and provided a useful defence against some predators, or even parasites (if also making them more vulnerable to others like fleas).
Is the T. rex skeleton real?
Scientists have revealed the world’s first ever complete T-rex skeleton – found after it fell to its death in a deadly duel with a triceratops. It has been described as ‘one of the most important paleontological discoveries of our time’ – and is the only 100\% complete T-rex ever found.
Is Stan the T. rex real?
“Stan”, also known by its inventory number BHI 3033, is a Tyrannosaurus rex fossil found in the Hell Creek Formation in South Dakota, just outside of Buffalo in 1987, and excavated in 1992. It is the fifth most complete T. rex fossil discovered to date, at more than 70\% bulk.
How did feathers develop?
Feathers are complex and novel evolutionary structures. Current hypotheses propose that they evolved through an invagination of the epidermis around the base of a dermal papilla, followed by increasing complexity of form and function. They evolved before birds and even before avian flight.
