By theMesozoic eustasy end of the Paleozoic Era, the slow but monumental process of assembling the supercontinent of Pangea was nearly complete. The final suturing of its continental blocks – through a series of massive orogenic events – reached full amalgamation in the early Triassic, setting the stage for the next dramatic chapter in Earth’s tectonic history. The Mesozoic Era soon witnessed the onset of rifting and fragmentation, initiated by subcrustal trapped heat and the long and complex breakup of Pangea that would eventually disperse and then sub-amalgamate its smaller fragment into vast larger landmass into the continents we recognize today. The history of sea level of Mesozoic is thus dominated by the hothouse climates and tectonics related to the end of one and the beginning of another Wilson cycle.
