Cryolophosaurus (meaning "cold crested lizard") is an extinct genus of theropod dinosaur that lived in Early Jurassic. The type species is Cryolophosaurus ellioti.
Discovery and naming[]
Cryolophosaurus has killed a Glacialisaurus, as another approaches and tries to get a bite out of.
The holotype (FMNH PR1821) was collected during the 1990-91 expedition by William R. Hammer and his team, on Mount Kirkpatrick. They were located in the siltstone of the Hanson Formation and dated to the Pliensbachian stage of the early Jurassic. In 1991, Elliot’s team discovered the remains of Cryolophosaurus in a rock formation and notified Hammer. The team recovered over 100 fossil bones, including those of Cryolophosaurus. These specimens were formally named and described in 1994 by Hammer and William J. Hickerson, in the journal Science. Hammer and Hickerson named the species C. ellioti after David Elliot, who had made the initial discovery of the fossils.

Description[]
The holotype (FMNH PR1821) is the only fully described specimen of Cryolophosaurus. The specimen consists of an incomplete skull and mandibles lacking most of their front half, nine maxillary teeth,a fragmentary sixth cervical centrum, 7-10 cervical vertebraes, several posterior cervical ribs, several anterior dorsal vertebrae, most mid and posterior dorsal vertebrae, several dorsal ribs, the fifth sacral vertebrae, three chevrons, many partial and complete caudal vertebrae and centra, two partial humeri, a proximal radius, a proximal ulna, a partial ilium, a proximal pubis, both ischia, the distal end of a tibia, the distal end of a fibula, and the astragalus and calcaneum. In 2013, new material of Cryolophosaurus was unearthed in Antarctica. It was a large, well-built theropod. The genus has been described by Roger Benson and colleagues as a top predator in Antarctica. It had slender proportions. Cryolophosaurus was estimated as being 6 to 7 m (19.7ft-23.0ft) in length by William R. Hammer & William J. Hickerson. A 2007 study by Nathan Smith revised the length to 6.5 m (21.3 ft). Its weight is 465 kilograms (1,025 lb). Smith and Benson noted that the holotype individual probably represents a sub-adult, so adults could have been larger. In 2016 Molina-Pérez and Larramendi gave a larger estimation of 7.7 meters (25.3 ft) and 780 kg (1.720 lbs).
Classification[]
It is classified as neotheropoda.
Paleoecology[]
Cryolophosaurus lived with Glacialisaurus ,a dimorphodontid, a synapsid, a herbivorous synapsid, and two unnamed sauropodomorphs.
In the media[]
- Cryolophosaurus appears in the first episode of Dinosaur Revolution. In the episode, as a mated pair look on their eggs a larger male appears and he attacks the resident male and eats the eggs. It later appears planning an attack on a lone Glacialisaurus. He tries to ambush, but the Glacialisaurus fell down the log the Cryolophosaurus chased its prey on and into the mud. As the Cryolophosaurus is being assaulted by a flock of giant mosquitoes, it runs towards a herd of Glacialisaurus, chasing off the dominant male. However, the lone Glacialisaurus survived, covered in hard mud that is mosquito-proof.
- Cryolophosaurus also appears in both Primal Carnage and Primal Carnage: Extinction. It has the ability to spit out poison in Primal Carnage, where it is simply an alternate skin for the Dilophosaurus in the game. It instead spits out acid in the sequel, Primal Carnage: Extinction.
- Cryolophosaurus appears in Warpath: Jurassic Park as one of the six unlockable dinosaurs. It can be unlocked after Triceratops, and right before Albertosaurus. Its move pattern was the same to that as Tyrannosaurus rex and Acrocanthosaurus. It has fast but weak attacks and combos. However, instead of biting, this Cryolophosaurus uses its crest to attack. It has 3 different colors: black, light orange, and green.
- Cryolophosaurus appears as a mob in both the PaleoCraft and Orespawn Minecraft mods.
- Cryolophosaurus appeared on Dinosaur Train, the individuals are King and Crystal.
- Cryolophosaurus also appeared in Dinosaur King.
- Cryolophosaurus appears in dinosaur world mobile, which appeared in Christmas update.
- It also appears in Jurassic World Evolution 2.
- In the film One Hundred Years Ahead (2024), a skull of Cryolophosaurus is shown in the future world. The drone tries to reconstruct its DNA.
