The Glacialisaurus is a massospondylid that lived in the early jurassic of Antarctica. It was a kind of prosauropod.
Description
Glacialisaurus is the first genus of sauropodomorph dinosaur known from Antarctica. Though only known from a few hind limb bones, these are enough to identify Glacialisaurus as a massospondylid sauropodomorph dinosaur, as well as possible close relative of Lufengosaurus from China. From the same fossil formation that the Glacialisaurus holotype remains are known from, the fossils of sauropod dinosaurs are also known. This is a clear indicator that the sauropod dinosaurs did not replace the earlier sauropodomorphs overnight, and that the sauropods and sauropodomorph dinosaurs co-existed together for quite some time. Predatory threats to Glacialisaurus potentially include Cryolophosaurus, a meat-eating theropod dinosaur that is known from the same Hanson Formation that Glacialisaurus is known from.
In Dinosaur Revolution
Glacialisaurus appeared in episode 1 "Evolution winners". A lone male meets a group of his species and tries to join them, but the alpha male of the group scares him off. After we met a Cryolophosaurus a few scenes back, the cryolophosaur chased and attacked the lone male Glacialisaurus, and the massospondylid fell off a log and broke his leg because of a swarm of mosquitos that was chasing him. The mosquitos attack the Cryolophosaurus instead, and in his struggle to flee, he scares off the alpha male Glacialisaurus from before, allowing the broken-legged male to become the new leader. In the end, the former alpha male Glacialisaurus is seen still being chased by the Cryolophosaurus and the swarm of mosquitos.
