New climate record found in fossil teeth shows Earth was hotter, greener in dinosaur age
SMRTR summary
Fossilized dinosaur teeth have revealed insights into prehistoric climate, showing CO₂ levels were 3-4 times higher than pre-industrial levels. Analysis of oxygen isotopes in tooth enamel found CO₂ concentrations reached 1,200 ppm in the Late Jurassic, compared to today's 430 ppm. The research indicates prehistoric Earth had twice the vegetation density of modern times. Some teeth contained evidence of volcanic eruptions, offering a new method for studying ancient climate conditions.
