The name Cryolophosaurus means "frozen crested reptile." The characteristic feature of this dinosaur is the large crest on the top of the skull, above the eyes. The nasal bones extend toward the back of the skull as ridges, and then join with the lacrimal bones to form a grooved crest which extends perpendicularly from the skull. Cryolophosaurus was discovered in the Jurassic Hanson Formation in the Transantarctic Mountains and represents the only theropod dinosaur to be found in Antarctica.
