A collection of dinosaur teeth hailing back to the Cretaceous and Jurassic periods has given scientists a new window into the world’s prehistoric climate. By studying an isotope of oxygen in the fossils to infer atmospheric carbon dioxide levels, a team led by geochemist Dingsu Feng of the Georg August University of Göttingen in Germany has reconstructed the very air …
