Paleontologists from the University of Witwatersrand have identified a new species of Triassic archosauromorph from fossils found in Antarctica's Shackleton Glacier region. Named Antarctosuchus boreas, this small, lizard-like predator lived during a time when Antarctica was a lush, forested environment following the Permian mass extinction.
The fossils include a nearly complete skull and skeletal fragments that show unique adaptations for burrowing and thermal regulation. This discovery provides critical evidence for the rapid diversification of terrestrial vertebrates in high-latitude Gondwana, suggesting that the Antarctic landmass served as a vital evolutionary laboratory for the ancestors of modern reptiles and dinosaurs.
