âA project to drill a 10-kilometre-deep hole in China 
will provide the best view yet of the turbulent 
Cretaceous period. Jane Qiu reports.â

âThe team analysed oxygen and carbon isotopes in 
fossil crustacean shells as a proxy for ancient 
temperature and carbon dioxide levels, finding that 
atmospheric CO2 levels doubled and then halved 
over 3 million years in the Late Cretaceous.â

The article also mentions that Cretaceous temperatures
plunged by 7 degrees C over a 10 million year period 
and of Cretaceous âsupergreenhousesâ and there is
a terrestrial record of the K/Pg extinction in these 
lakes sediments.
