Tyrannosaurus rex holotype specimen at the Carnegie Museum of Natural History, Pittsburgh. Credit: / CC BY-SA 3.0 Scientists have successfully reconstructed the prehistoric air that dinosaurs once breathed by analyzing fossilized teeth, offering an unprecedented look into Earth’s ancient climate. The groundbreaking study used geochemical markers preserved in tooth enamel to estimate atmospheric carbon dioxide levels during the Mesozoic Era, bringing researchers a step closer to understanding how the environment evolved over millions of years. By studying oxygen isotopes trapped in the dental enamel of dinosaurs, researchers were able to infer the...
