tyrannosaur
The fossilized remains of Sue, the most complete Tyrannosaurus rex skeleton in the world, on display at the Field Museum of Natural History, Chicago.
The feathered tyrannosaur Dilong was discovered in the rock deposits of the Yixian Formation, located in the western Liaoning province of China.1
These fossils date back to the Early Cretaceous period, approximately 128 million to 127 million years ago. As a primitive member of the tyrannosaur group, Dilong provides significant evidence that these dinosaurs possessed feathers, likely for insulation.1
