Geologic Time Scale: Jurassic Period
(201.3 to 145 million years ago)
The Jurassic Period constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata (layers) from the period from the period were first identified. The Jurassic Period starts with the major Triassic-Jurassic extinction event and the supercontinent Pangaea had began rifting in two land masses: Laurasia (North America, Europe, and Asia) to the north and Gondwana (South America, Africa, India, Australia, Anartica, and Madagascar) to the south.
The first true crabs, rays, frogs, salamanders, lizards, crocodiles, and birds appear in the Jurassic Period. Crocodylomorphs made the transition from a terrestial to an aquatic life. The Oceans were inhabited by marine reptiles such as ichthyosaurs and plesiosaurs, while pterosaurs were the dominant flying vertebrates.
Tithonian Age/Stage
Late Jurassic: 152.1 to 145.0 million years ago
The Tithonian Stage was the last stage of the late or upper Jurassic Period. named in 1865 by German stratigrapher Albert Oppel after the Greek mythological figure Tithonus, son of Laomedon of Troy and fell in love with Eos Greek goddess of dawn. The Tithonian is in contact with the dawn of Cretaceous.
