Marine creatures like sharks existed in the Jurassic. Marine reptiles like icthyosaurs, plesiosaurs, and thalattosuchians also existed. Thalattosuchians are fully marine reptiles.
Probably the most interesting sights during the Jurassic Period would be the plethora of dinosaurs. The world was dominated by these creatures at that time.
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.
An ichtyosaurus is a marine reptile that lived in the Jurassic period.
The Allosaurus lived 150 million years ago. That was during the Jurassic period. The Jurassic period was part of the Mesozoic era.
The Jurassic Period was named after the Jura Mountains, which are located in Europe. This period lasted from approximately 201.3 to 145 million years ago and is known for the dominance of dinosaurs and the diversification of marine life.
Earthquakes did appear during the Jurassic period along with volcano eruptions.

Brontosaurus lived during the Jurassic Period
No, humans did not exist during the Jurassic period. This time period, which occurred about 201 to 145 million years ago, was dominated by dinosaurs and other prehistoric creatures. Humans did not evolve until much later, closer to about 300,000 years ago.
Ammonites are very common fossils from the Jurassic Period. They were dominant in the ocean during and before the Jurassic Period.
Several organisms diversified during the Jurassic period. Crocodiles became larger and more diverse. Dinosaurs and birds diversified and thrived. Of all the organisms in the Jurassic Period, plants diversified the most.
The breakup of the supercontinent Pangaea and the opening of the Atlantic Ocean was the major geologic event during the Jurassic time period. This led to significant changes in global climate and ocean circulation, as well as the evolution and diversification of marine and terrestrial life forms.
