T. rex descended from feathered ancestor

T. rex descended from feathered ancestor (New Scientist: 06-Oct-04)
Chinese palaeontologists have uncovered the most complete fossil yet of an ancestral tyrannosaur, and found that filamentary protofeathers covered its body. Feathers and protofeathers had been found on related dinosaurs, but not on an early tyrannosauroid. The new animal, named Dilong - from the Chinese words for "emperor dragon" - was lightly built and about 1.5 metres long. It lived between 128 and 139 million years ago, predating Tyrannosaurus rex by 60 to 70 million years.
