Dinosaur Teeth Unlock Secrets of Earth’s Ancient Climate

Dinosaur Teeth Unlock Secrets of Earth’s Ancient Climate

A new method allows scientists to reconstruct carbon dioxide levels and photosynthesis from fossilized tooth enamel. A surprising new line of evidence is providing fresh insights into Earth’s ancient climate. Fossilized dinosaur teeth reveal that the atmosphere during the Mesozoic era (between 252 and 66 million years ago) contained much higher levels of carbon dioxide [...]

Scientists Uncover Mesozoic Carbon Dioxide Levels and Photosynthesis Through Dinosaur Tooth Enamel Analysis

During the Mesozoic era, from 252 to 66 million years ago, analyses of the oxygen isotope composition in dinosaur teeth revealed that the atmosphere contained significantly more carbon dioxide than it does today, with global plant photosynthesis levels roughly double those of the present. Fossil teeth of Camarasaurus from the Morrison Formation in the US. [...] The post Scientists Uncover Mesozoic Carbon Dioxide Levels and Photosynthesis Through…

Scientists Reconstruct Mesozoic Carbon Dioxide Levels and Photosynthesis from Dinosaur Tooth Enamel

The atmosphere of Earth during the Mesozoic era, between 252 and 66 million years ago, contained far more carbon dioxide than it does today and total photosynthesis from plants around the world was twice as high as it is today, according to an analysis of oxygen isotope composition of dinosaur teeth.
