Why did T Rex have feathers?
Paleontologists think feathers may have first evolved to keep dinosaurs warm. But while a young T. rex probably had a thin coat of downy feathers, an adult T. rex would not have needed feathers to stay warm.
What was the original purpose of feathers?
They evolved before birds and even before avian flight. Thus, early feathers functioned in thermal insulation, communication, or water repellency, but not in aerodynamics and flight. Among extinct life-forms, feathers are no longer considered a unique and diagnostic characteristic of birds.
When did dinosaurs start having feathers?
180 million years ago
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.

Archaeopteryx, the first good example of a “feathered dinosaur”, was discovered in 1861. The initial specimen was found in the solnhofen limestone in southern Germany, which is a lagerstätte, a rare and remarkable geological formation known for its superbly detailed fossils.
