Late Jurassic
[2] In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age.The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock:[citation needed] During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south.The result of this break-up was the spawning of the Atlantic Ocean.[citation needed] This epoch is well known for many famous types of dinosaurs, such as the sauropods, the theropods, the thyreophorans, and the ornithopods.Other animals, such as some crocodylomorphs and the first birds, appeared in the Jurassic.
