Dinosaur During The Jurassic Period
Jurassic Dinosaurs: Introduction (Scroll down to see the dinos!) The Jurassic Period is the second of the three periods of the Mesozoic Era. At the end of the preceding Period - the Triassic Period - there had been a mass extinction of species. This was probably caused by widespread volcanic activity.
During that tumultuous time, 50% of all species became extinct, including the dinosaurs. The Jurassic Period stands as a significant chapter in Earth's history, recognized for the emergence and diversification of iconic dinosaurs. This geological time frame witnessed profound transformations in the planet's landscape and life forms, laying the groundwork for many dominant species.
This is, as the picture says, "Dinosaurs Of The Jurassic Period".
Dinosaurs diversified greatly after the extinction at the end of the Triassic removed most of their competition. We have bones and/or footprints of most of the major lineages of dinosaurs dating back to the Early Jurassic: carnivorous theropods; the enormous sauropods with their long necks and long tails; armored dinosaurs, including plated stegosaurs and scute-bearing ankylosaurs; and. During the Jurassic Period, dinosaurs went from an unimportant group to ruling our planet.
But exactly how they did it remains an unsolved mystery. 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.

On land, dinosaurs and flying pterosaurs dominated, and birds made their first appearance. The Jurassic Period is divided into three epochs: Early, Middle, and Late. Similarly, in stratigraphy, the Jurassic is divided into the Lower Jurassic, Middle Jurassic, and Upper Jurassic series.
Geologists divide the rocks of the Jurassic into a stratigraphic set of units called stages, each formed during corresponding time intervals called ages. Stages can be defined globally or regionally. Jurassic Period The Jurassic period was the middle of the three periods into which we divide the Mesozoic Era (the previous period being the Triassic period, and the next period being the Cretaceous period), and occured between 213 million and 144 million years ago.

During the entire Jurassic period, dinosaurs were the dominant land animals, and many of the more familiar types of dinosaurs. Overall, the Jurassic Period was a time of significant change and evolution, both in terms of the Earth's geography and the life that inhabited it. The dinosaurs that lived during this period were some of the most impressive creatures to ever walk the planet, and their legacy continues to fascinate and inspire people today.
Major Dinosaur Groups The Jurassic period was a golden time for. The Jurassic period saw dinosaurs such as Allosaurus and Apatosaurus rise to prominence. The Triassic, Jurassic, and Cretaceous periods are important stages in dinosaur and plant evolution.
During the Mesozoic Era, dinosaurs, birds, and mammals evolved and diversified across the changing Earth. Each period, from the Triassic to the Cretaceous, had unique climate, geography, and dominant species.
