A drop in CO2 caused many plant eaters to make a long journey all the way from South America to Greenland. Sounds jaw dropping right? It was a 10,000 kilometer journey, or around 6,200 miles. At the rate the dinosaurs were going it would take 20 years to reach there. These dinosaurs were called “Sauropodomorph” and they were the early plant-eating dinosaurs. The carbon levels were really high in the deserts and rainforests. While traveling to Greenland the Herbivores didn’t have much food due to the vast deserts. There was a sudden drop in CO2 in Greenland and the reason is still unknown.
