文摘

•: The palaeo-pCO₂ was estimated based on 4 Cheirolepidiaceae from Jiuquan Basin.
•: The atmospheric CO₂ content was 1060–531 ppmv during the late Early Cretaceous.
•: The δ¹³Cp values indicated a water-stressed environment.
•: A non-significant correlation between the δ¹³Ca and the pCO₂ was proposed.
