Guanlong

About 3 to 3.5 metres (10 to 11.5 feet) long and weighed around 125 kilograms (276 pounds). That's about as long as a small car.31

Yes, it almost certainly had a coat of primitive feathers, like its close relative Dilong. The feathers were probably simple and hair-like.43

It was a carnivore that hunted smaller dinosaurs, mammals and other animals. It may have also been hunted by larger predators like Yangchuanosaurus.4

The large, fragile crest on its head was probably used for display, like to attract mates or show off to other Guanlong. It was too thin and delicate to be a weapon.43

Yes, it is a dinosaur. It belongs to the group Theropoda and is a type of tyrannosauroid, the same group that includes T. rex.13

It lived during the Late Jurassic Period, about 160 to 154 million years ago. That's about 95 million years before T. rex appeared.13

Scientists don't know its exact speed, but as a small, lightweight theropod with long legs, it was probably a fast runner. No source gives a specific number.3

No, it was much smaller. Guanlong was only about 3 metres long, while T. rex could be over 12 metres long. Guanlong lived about 95 million years before T. rex.43
