Dilong paradoxus


Dilong is a small basal tyrannosauroid from the Early Cretaceous of China. Compared to its descendants of the late cretaceous such as Tyrannosaurus, it has a light slender body with long arms and 3 digits per hand. One of the referred specimen show traces of filamentary structures on the tail, indicating that Dilong was probably covered with primitive hair-like feathers.
