Jurassic period of the Mesozoic era is characterized by -The Mesozoic era, the age of reptiles, is divided into the Triassic, Jurassic and Cretaceous periods.
In the Jurassic period the dinosaurs were dominant, which is why it is called the age of dinosaurs.
Gymnosperms, especially cycads and conifers, were the dominant plants.
The first birds appeared in this period; Archaeopteryx is known from Jurassic rocks.
The radiation of reptiles and the origin of mammal-like reptiles belong to the Permian and Triassic periods, and the first dinosaurs appeared in the Triassic.
The extinction of the dinosaurs and the rise of angiosperms belong to the Cretaceous period.
So the Jurassic period is characterised by gymnosperms being the dominant plants and the appearance of the first birds.
