Jurassic

Biology

The second geological period of the Mesozoic era. It followed the Triassic, which ended about 201 million years ago, and extended until the beginning of the Cretaceous period, about 145 million years ago. It was named in 1829 by A. Brongniart after the Jura Mountains on the borders of France and Switzerland. Jurassic rocks include clays and limestones in which fossil flora and fauna are abundant. Plants included ferns, cycads, ginkgos, rushes, and conifers. Important invertebrates included ammonites (on which the Jurassic is zoned), corals, brachiopods, bivalves, and echinoids. Reptiles, notably the dinosaurs, dominated the vertebrates and the first flying reptiles—the pterosaurs—appeared. The birdlike dinosaur, Archaeopteryx, also made its appearance.

Geology and Earth Sciences

One of the three Mesozoic periods: it lasted from 199.6 to 145.5 Ma ago, following the Triassic and preceding the Cretaceous. The Jurassic period is subdivided into eleven stages (Hettangian, Sinemurian, Pliensbachian, Toarcian, Aalenian, Bajocian, Bathonian, Callovian, Oxfordian, Kimmeridgian, and Tithonian), with clays, calcareous sandstones, and limestones being the most common rock types. Brachiopods, bivalves, and ammonites are abundant fossils, along with many other invertebrate stocks. Reptiles flourished on land and in the sea, but mammals were relatively insignificant and presumed to have been predominantly nocturnal. The first birds, including Archaeopteryx, appeared in the Late Jurassic.

Geography

The middle period of Mesozoic time stretching approximately from 190 to 136 million years bp.
