Plant-eating dinosaurs arrived in the Dinosaur TRex school enrollment First limited Shirt Northern Hemisphere millions of years after their flesh-eating cousins, a possible delay caused by climate change, a new study suggests.

A new way of calculating the date of dinosaur fossils found in Greenland shows that the herbivores, called sauropodomorphs, are around 215 million years old, according to a study in Monday’s Proceedings of the National. Academy of Sciences. The fossils were previously thought to be 228 million years old.
That changes the Dinosaur TRex school enrollment First limited Shirt way scientists think about dinosaur migration. All dinosaurs first appeared to first develop in what is now South America about 230 million years ago or so. Then they wander north and around the world. New research shows that not all dinosaurs are able to migrate at the same time. So far, scientists have yet to find any examples of the earliest plant-eating family of dinosaurs in the northern hemisphere that is more than 215 million years old. One of the best examples is the Plateosaurus, a 23-foot (7-meter) long bipedal vegetarian that weighs 8,800 pounds (4,000 kg).
Kent used changes in the Earth’s magnetism in the soil to more accurately date Greenland fossils. That highlights the time-migration gap, some outside experts report both on dinosaurs and the ancient climate. Kent’s theory of climate change is that the difference in dinosaur migration “is amazing because it brings it back to contemporary issues,” Irmis said. Although the study is significant, there is a potential flaw, said Paul Sereno, a dinosaur expert at the University of Chicago: Just because none of the Dinosaur TRex school enrollment First limited Shirt fossils of the herbivore are more than 215 million years old Found in the Northern Hemisphere, this does not mean that sauropodomorphs are absent. The fossils may not exist, he said.
For decades, the popular hypothesis for dinosaur extinction was that an asteroid from the belt between Mars and Jupiter crashed into the planet, causing a cataclysm and wiping out most of life. on the planet. I’ve never heard much about nature, dinosaurs, or anything like that. Maybe you should call your program The So-called News because I haven’t heard about everything. Or please talk more about dinosaurs and cool stuff.
