Issi saaneq, a medium-sized long-necked sauropodomorph, is a newly discovered species of plant-eating dinosaur from Greenland, which lived during the Late Triassic (214 million years ago).
The remains of these dinosaurs were recovered in expeditions during the 1990s and were originally assigned to Plateosaurus; however, as this article has explored, enough anatomical differences in the skull bones allowed it to be recognized as a new genus and species. Together with the European Plateosaurus, Issi saaneq form the group of plateosaurid sauropodomorphs.
This new dinosaur increases the diversity of dinosaurs during the Late Triassic and allows us to start retracing the evolutionary routes and timing for the iconic group of sauropods that roamed the Earth for almost 150 million years. View this paper
