Guanlongs were a small Tyrannosauridae and their hunting attribute are similiar to raptors (dromaeosaurs), because they hunt in packs. Their fossils are found in Dzungaria, China. Guanlongs are blue with silver stripes, they have some orange around the sides of their heads and had quills on the back of their neck and back.
Ice Age: Dawn of the DinosaursEdit
A number of Guanlong had survived the comet showers that had long since wiped out the dinosaurs as a whole, escaping to a vast subterranean world where dinosaurs of all kinds lived as they had in the past.
One such pack of Guanlong resided in the Plates of Woe, a rock formation within the Dinosaur World, where they found a herd of mammals consisting of a pair of mammoths, a pair of possums, a saber-tooth tiger and a weasel that guided them. One of the mammoths, a female named Ellie, was pregnant and went into labor upon entering the Plates: the Guanlong went on the hunt to find Ellie. They were prevented from making a meal of her by the joint efforts of Manny and Diego.
