Story summary

German researchers developed a method to analyze oxygen isotopes in fossilized dinosaur teeth.
The study found CO2 levels were four times higher in the Late Jurassic and three times higher in the Late Cretaceous.
Global photosynthesis was also twice as high, influencing climate dynamics.
This method enhances understanding of ancient climates and Earth's atmospheric history.
