| 21. | Angiosperms evolved in the northern Gondwana / southern Laurasia during the Early Cretaceous and radiated worldwide.
|
| 22. | Pangaea gradually split into a northern continent, Laurasia, and a southern continent, Gondwana.
|
| 23. | The Hercynian orogeny was the result of a continent-continent collision between Laurasia and Gondwana.
|
| 24. | Consequently, trade winds moved water away from Gondwana towards Laurasia in the northern Panthalassa Equatorial Current.
|
| 25. | In the Jurassic, Pangaea split into Laurasia and Gondwana, with Avalonia as part of Laurasia.
|
| 26. | In the Jurassic, Pangaea split into Laurasia and Gondwana, with Avalonia as part of Laurasia.
|
| 27. | In the Cretaceous, Laurasia broke up into North America and Eurasia with Avalonia split between them.
|
| 28. | Next Proto-Laurasia itself split apart to form the continents of Laurentia, Siberia and Baltica.
|
| 29. | Diadectids are otherwise absent from eastern Laurasia, which may reflect their low diversity at the time.
|
| 30. | When the western margins of Panthalassa were reached intense western boundary currents would form the Eastern Laurasia Current.
