The Jurassic constitutes the middle period of the Mesozoic Era as well as the eighth period of the Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified.
Jurassic Period, second of three periods of the Mesozoic Era. Extending from 201.3 million to 145 million years ago, the Jurassic was a time of global change in the continents, oceanographic patterns, and biological systems.
The Jurassic period (199.6 million to 145.5 million years ago) was characterized by a warm, wet climate that gave rise to lush vegetation and abundant life. Many new dinosaurs emerged—in great ...
The Jurassic period was the second segment of the Mesozoic era. It occurred from 201.3 million to 145 million years ago, following the Triassic period and preceding the Cretaceous period.
During the Jurassic period, the climate was warm and wet, leading to an abundance of resources that could sustain large animal and plant species. It was so warm that there were no ice caps, and instead, forests grew in the cooler areas closer to the poles.
Jurassic Period, Interval of geologic time, 201.3–145 million years ago, that is one of the three major divisions of the Mesozoic Era. It was preceded by the Triassic Period and followed by the Cretaceous .
Thanks to the movie Jurassic Park, people identify the Jurassic period, more than any other geological timespan, as a dinosaur period. The Jurassic is when the first gigantic sauropod and theropod dinosaurs appeared on Earth, a far cry from their slender, man-sized ancestors of the preceding Triassic period.
The Jurassic Period is a period of time in the geologic time scale. It’s named after the Jura Mountain range on the France / Switzerland border. Rocks in this region were formed during the Jurassic Period. The Jurassic Period began 201.3 million years ago (Mya) and ended 145 Mya.
The Jurassic Period is divided into three epochs: Early Jurassic (201.3 million to 174.1 million years ago), Middle Jurassic (174.1 million to 163.5 million years ago), and Late Jurassic (163.5 million to 145 million years ago). (These intervals are sometimes referred to as the Lias, Dogger, and Malm, respectively.)
The Jurassic began about 201 million years ago at the end of the Triassic Period and ended 145 million years ago at the start of the Cretaceous Period. The Jurassic was named for the Jura Mountains between France and Switzerland, where rocks of the period were first studied.
