The Jurassic Period is defined as the period of time between 200 million years ago to 145 million years ago.
Jurassic Park was set in modern times and not a geological period...however the dinosaurs were from the Jurassic Period.
The Jurassic period ended 145+/- 4 million years ago. It took place between the Triassic period and the Cretaceous period.
Stegosaurus
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.
They have been around since the Cambrian Period and a lot of them are extinct.
It depends. If Seismosaurus hallorum proves to be really a Diplodocus, than that would be the longest known specimen, with a length of about 33 meters. Otherwise, the longest known Diplodocus is about 27-30 meters long.
The diplodocus lived 150 million years ago in the late Jurassic period.
The diplodocus lived 150 million years ago in the late Jurassic period.
Pterodactylus fossils range from between 150.8 and 148.5 million years. Thus, they existed for at least 2.3 million years during the Jurassic period.
The first phase began in the Early-Middle Jurassic (about 175 Ma).
since the Cretacious period
