The Mesozoic Era, comprising the Triassic (∼252–201 Ma), Jurassic (∼201–145 Ma), and Cretaceous (∼145–66 Ma) periods (Cohen et al., 2013), marked a transition from the last supercontinent Pangaea toward today's fragmented continental configuration and from “old” (Paleozoic) to “new” (Cenozoic) biota that are now integral parts of the modern world (e.g ...

Mesozoic. Pangea began to break up during the Triassic, while Gondwana moved northward taking Antarctica way from the South pole region. Subduction continued along the Pacific margin, and Triassic strata was deposited along the Transantarctic Mountains and the Antarctic Peninsula, including the Trinity Peninsula Group, the Legoupil Formation, …The overall picture is thus quite clear: throughout Mesozoic time there was a continuous dying out and renewal of dinosaurian life. It is important to note that extinction is a normal, universal occurrence. Mass extinctions often …
