The new dinosaur honours the local Inuit language - its scientific name Issi saaneq means 'Cold Bone'. Its remains were found in Jameson Land, east Greenland.

For the first time, researchers have accurately dated the arrival of the first herbivorous dinosaurs in East Greenland. A new study shows extreme climatic conditions slowed down their trek from the southern hemisphere. Their long walk was only possible because as CO2 levels dropped suddenly, the Earth’s climate became less extreme. A snail could have crawled its way faster. 10,000 kilometers (6,213 miles) over 15 million years—that’s how long it took the first herbivorous dinosaurs to make their way from Brazil and Argentina. The herbivorous dinosaurs first appeared in Brazil and Argent...

 E-Mail For the first time, two researchers--one from the University of Copenhagen and the other from Columbia University--have accurately dated the arrival of the first herbivorous dinosaurs in East Greenland. Their results demonstrate that it took the dinosaurs 15 million years to migrate from the southern hemisphere, as a consequence of being slowed down by extreme climatic conditions. Their long walk was only possible because as CO2 levels dropped suddenly, the Earth's climate became less extreme. A snail could have crawled its way faster. 10,000 km over 15 million years--that's how long...

February 24, 2021 at 6:00 am A drop in carbon dioxide levels may have helped sauropodomorphs, early relatives of the largest animal to ever walk the earth, migrate thousands of kilometers north past once-forbidding deserts around 214 million years ago. Scientists pinpointed the timing of the dinosaurs’ journey from South America to Greenland by correlating rock layers with sauropodomorph fossils to changes in Earth’s magnetic field. Using that timeline, the team found that the creatures’ northward push coincides with a dramatic decrease in CO 2, which may have removed climate-related b...

Estimates of when herbivorous dinosaurs traversed North America to reach Greenland have been refined, and the study reveals how a dip in atmospheric CO₂ may have helped them along the journey.
