virtually all the major landmasses of the world were collected into thesupercontinentofPangea. Terrestrial climates were predominately warm and dry (though seasonalmonsoonsoccurred over large areas), and the Earth’s crust was relativelyquiescent. At the end of the Triassic, however,plate tectonicacti...
