First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.. The Tethys Ocean (/ ˈ t iː θ ɪ s, ˈ t ɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era.
Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B (MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 years ago at the beginning of the Holocene and after the end of the Younger Dryas.

Rheic Ocean, the Paleozoic ocean between Gondwana and Laurussia; Slide Mountain Ocean, the Mesozoic ocean between the ancient Intermontane Islands (that is, Wrangellia) and North America; South Anuyi Ocean, Mesozoic ocean related to the formation of the Arctic Ocean; Tethys Ocean, the ocean between the ancient continents of Gondwana and Laurasia
the development of histic and spodic palaeosols, fossil soils which are typical of a tropical humid climate with more water entering through precipitation than leaving through evapotranspiration; hygrophytic palynological (fossil pollen) assemblages that reflect vegetation more adapted to a humid climate; the widespread presence of amber.

The Earth is formed out of debris around the solar protoplanetary disk. There is no life. Temperatures are extremely hot, with frequent volcanic activity and hellish-looking environments (hence the eon's name, which comes from Hades). The atmosphere is nebular. Possible early oceans or bodies of liquid water.
Through study of Pacific Ocean sediments, other researchers have shown that the transition from warm Eocene ocean temperatures to cool Oligocene ocean temperatures took only 300,000 years, [100] which strongly implies that feedbacks and factors other than the ACC were integral to the rapid cooling.
The Cambrian (/ ˈ k æ m b r i. ə n, ˈ k eɪ m-/ KAM-bree-ən, KAYM-) is the first geological period of the Paleozoic Era, and the Phanerozoic Eon. [5] The Cambrian lasted 51.95 million years from the end of the preceding Ediacaran period 538.8 Ma (million years ago) to the beginning of the Ordovician Period 486.85 Ma.
The Carboniferous (/ ˌ k ɑːr b ə ˈ n ɪ f ər ə s / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic era that spans 60 million years from the end of the Devonian Period 358.86 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma.
