Palynology and sea surface temperature reconstruction for the mid-Cretaceous ...

The mid-Cretaceous is thought to be a greenhouse world with significantly higher atmospheric pCO2 and sea-surface temperatures as well as a much flatter latitudinal thermal...白垩纪中期（mid-Cretaceous）被认为是一个温室气候世界，其时大气二氧化碳分压（pCO₂）与海表温度均显著偏高，且纬向热梯度远为平缓……
