About Issi
Issi (meaning "cold" in Greenlandic) is a plateosaurid dinosaur from the Late Triassic Fleming Fjord Formation of Greenland. It contains one species, Issi saaneq; the full binomial name means "cold bone". Fossils of Issi were previously assigned to the species Plateosaurus trossingensis, but new finds allowed for a reassessment of that material that showed that it possessed features thought to be exclusive to Brazilian sauropodomorphs such as Unaysaurus and Macrocollum. This ultimately led to the designation of Issi as a distinct genus in 2021. This taxon is the first non-avian dinosaur described from Greenland.
