The Jurassic Period is defined as the period of time between 200 million years ago to 145 million years ago.
The Jurassic period ended 145+/- 4 million years ago. It took place between the Triassic period and the Cretaceous period.
Allosaurus fossils date to between 155 and 150 million years ago. This was during the Kimmeridgian and Tithonian stages of the Jurassic period. The Jurassic was the second period of the Mesozoic era.
The Jurassic Period lasted from 199 million years ago to about 145 million years ago.
The Jurassic period extended from 200 million BCE to 146 million years BCE. It lasted 54 million years.
The Allosaurus lived 150 million years ago. That was during the Jurassic period. The Jurassic period was part of the Mesozoic era.
The diplodocus lived 150 million years ago in the late Jurassic period.
The diplodocus lived 150 million years ago in the late Jurassic period.
The Triassic Period occurred before the Jurassic Period. The Triassic Period lasted from about 251 million to 201 million years ago, while the Jurassic Period followed, lasting from about 201 million to 145 million years ago.
Diplodocus lived during the Late Jurassic period, around 154-152 million years ago.
The Triassic period came before the Jurassic period in geologic time. The Triassic period lasted from around 251 million to 201 million years ago, followed by the Jurassic period, which lasted from around 201 million to 145 million years ago.
The Jurassic period was the middle period of the Mesozoic era. It lasted from 199 to 145 million years ago. The Jurassic was divided into 11 stages, the first being the Hettangian and the last was the Tithonian.
Dinosaurs lived in the Jurassic Period over 145 to 200 million years ago. Dinosaurs became extinct during the Triassic period.
