Guanlong wucaii was a carnivorous dinosaur that lived during the Late Jurassic period, approximately 156 million years ago, in the Oxfordian, in what is now Asia.
This dinosaur is notable for being one of the first known members of the tyrannosauroid group, the precursors of the famous Tyrannosaurus rex.
In terms of size, the Guanlong wucaii was relatively small compared to its better-known descendants. Fossils indicate that it reached a length of approximately 3 meters from head to tail. Its weight is estimated at around 70 to 100 kilograms.
The Guanlong wucaii is characterized by a distinctive crest on the top of its head, which possibly had display or communication functions. This crest was hollow and was probably used to attract mates or to demonstrate dominance among individuals of its species.
This bipedal dinosaur possessed relatively long forelimbs with three fingers, which were useful for grasping and manipulating prey. Its hind legs were strong and muscular, adapted for rapid locomotion, suggesting that the Guanlong wucaii was an agile and active hunter.
The discovery of the Guanlong wucaii has provided valuable information about the early evolution of tyrannosauroids, showing how these dinosaurs developed characteristics that would later be perfected in their gigantic Cretaceous descendants.
