The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
The common consensus is that dinosaurs dominated the land, being the most diverse large animals, and reaching huge sizes. In the oceans, large marine creatures included plesiosaurs, pliosaurs, ichthyosaurs (during the Jurassic and early Cretaceous), and mosasaurs (during the Cretaceous). The skies were ruled by pterosaurs. Coniferous trees were the primary large plants.
They were dominant during the mesozoic era, which was made up of the Triassic, Jurassic, and Cretaceous periods.
Dinosaurs.
There is no animal called the sitta osaurus. There is however, a stegosaurus. A stegosaurus was a herbivore that lived during the Jurassic and Cretaceous periods.
During the Late Jurassic and Early Cretaceous.
Ammonites are very common fossils from the Jurassic Period. They were dominant in the ocean during and before the Jurassic Period.

Theoretically, Pangaea existed during the Jurassic Period. If you are familiar with the Michal Cricton novels, you are aware that during the Jurassic, the dinosaurs flourished. The Jurassic is the second element of the Mesozoic Period (Triassic, Jurassic, and Cretaceous). You should be aware that the dinosaurs are theorized to have died off at the end of the Cretaceous (look into KT Boundary Theory).
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
There were three periods during the mesozoic era; the Triassic, Jurassic and Cretaceous.
Jurassic, Triassic, Cretaceous/The Mesozoic (all 3 in 1)
The type of animal that lived only during the Mesozoic Era (Age of Reptiles) were the dinosaurs. They evolved during the late Triassic and the Jurassic periods, and were the largest land creatures during the Cretaceous period of the era.
