Glacialisaurus was a sauropodomorph (pre-sauropod) whose fossils were found by Field Museum scientists in Antarctica. When Glacialisaurus lived, Antarctica experienced several months of around-the-clock darkness and then months of solid daylight, just as it does today. But it wasn't covered in ice—Earth had no polar ice caps back then.
