Plesiosaurs, apatosaurus (just about all the sauropods), praeornis, archaeopteryx (a Jurassic bird), Brachyopomorpha, Stephanoceras, Pleurosaurus--most of the Jurassic species did not survive beyond the Jurassic.
after Jurrasic period it is the Cretaceous period
Andrewsarchus possibly the largest land-dwelling carnivorous mammal known ever to exist. Lived 45-36 million years ago.Had a length from the snout to the back of the pelvis of about 3.4 m and a height from the ground to the shoulder or middle of the back of about 1.8 m. Weighted about 1000-1800 kg.
the smallest dinosaur ever discovered so far is the compsongnathus this animal lived in the Jurassic period and the largest dinosaur ever discovered is argentinosaurus it weight 100 tons!!!!
The Middle Jurassic Epoch (175.6 - 161.2Ma) was in the Jurassic Period (199.6 - 145.5Ma).
During the Jurassic period, the atmosphere was warmer and had higher levels of oxygen compared to today. There were lush forests with a diverse range of plant and animal species, including dinosaurs and early mammals. The climate was relatively stable and supported the evolution of many iconic prehistoric creatures.
No!!! There were no people alive in the Jurassic period.
The Jurassic Period followed the Triassic.
The Allosaurus lived 150 million years ago. That was during the Jurassic period. The Jurassic period was part of the Mesozoic era.
jurassic The Triassic was the earliest period of the Mesozoic, followed by the Jurassic then the Cretaceous. The Cretaceous was of the greatest duration.
After the jurassic period started the Mesozoic Era.
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
The Jurassic period is named after the Jura Mountains in Switzerland where significant geological strata from this time period were first studied. These rocks contain abundant fossils from the Jurassic period, which lasted from approximately 201 to 145 million years ago.
