The triassic-jurassic boundary is similar to the permo-triassic boundary in that the global climate was not radically altered, though a major extinction of terrestrial vertebrates occurred with the end of the triassic and the beginning of the jurassic, pangea continued to break apart, inevitably affecting the climate, though not as radically as it. The end-triassic mass extinction marked the transition between the triassic to the jurassic period and the rise of the large herbivorous dinosaurs, such as the diplodocus the extinction meant that previously abundant species were cleared from ecological niches which allowed dinosaurs to move in with little competition from other animals.
