Late Jurassic

Pangaea had begun to break up by the Late Jurassic, but Gondwana remained essentially intact. Some communication with northern faunas remained, however, as similar genera of dinosaurs are found in Late Jurassic rocks of North America and Africa. Asia was separated from Western Europe and shows a certain degree of endemism in its terrestrial fauna (Russell, 1993). Late Jurassic mammals are known from Western Europe, Asia, Africa, and North America. As previously mentioned, multituberculates are diverse in Late Jurassic faunas. Most characteristic are the diverse suites of "plagiaulacidan" multituberculates and "eupantotherians"; docodontans, "symmetrodontans," and "triconodonts" are also present, but are generally less abundant and not so diverse.
