New study of fossils suggests arrival in northern hemisphere long after meat-eating cousins
Plant-eating dinosaurs probably arrived in the northern hemisphere millions of years after their meat-eating cousins, a delay likely caused by climate change, a new study has found.
A new way of calculating the dates of dinosaur fossils found in Greenland show that the plant eaters, called sauropodomorphs, were about 215m-years-old, instead of as much as 228m-years-old as previously thought, according to a study in Monday’s Proceedings of the National Academy of Sciences.
