酷東西

趣味知識

Issi saaneq is the northernmost sauropodomorph dinosaur ever found from the Late Triassic.3

Its fossils include two almost complete skulls, one from a middle-stage juvenile and one from a late-stage juvenile or subadult.1

Issi saaneq lived about 214 million years ago, during the Norian stage of the Triassic Period.1

It was a plateosaurid, a close relative of Plateosaurus from Europe.2

The fossils were collected from the Malmros Klint Formation, which was once a lake shore environment.1

Issi saaneq was named in 2021 by Beccari and colleagues, making it a relatively new dinosaur discovery.2

發現: The first skull was found in 1991 in Greenland and was originally thought to be Plateosaurus. In 2021, scientists Beccari, Mateus, Wings, Milàn, and Clemmensen studied it and named it Issi saaneq, a new species.1 2
仍有爭議: Scientists are not sure exactly what the rest of Issi saaneq's body looked like, because only skulls have been described so far.3
