By means of the TEX-86 proxy, which is independent from changes in the chemistry and oxygen isotopic composition of ambient seawater, Forster et al. obtained the Mid-Cretaceous (Albian-Santonian) (sea surface temperatures) (SSTs) record of Demerara Rise, which was located in the western tropical Atlantic Ocean during Mid-Cretaceous. The factors driving the climate changes are compositive, but mainly the variation of angle between the earth axis and the equator, the strength of the sun’s radiation and the action of materials and structures in deep-earth level. Otherwise, any independent event hardly affects the global climate. Although climate does not directly influence the organic evolution, palaeoclimate plays an important role in studying major geological events including stratigraphic boundary, and fossil is, therefore of the most critical indexes of reconstructing the palaeoclimate.
