Plants began to evolve on Earth approximately 435 to 500 million years ago.However, the Mesozoic era was a time where the plant quickly enough thought .the ' Mesozoic era spans approximately 165 million years, covering three main geological periods of time. Triassic and Jurassic and Cretaceous.

During the Mesozoic era, dinosaurs were predominant life force, but the majority of the dinosaurs would not have survived without an abundance of life végétale.Malgré popular belief, most of the dinosaurs were phytophagous. At the end of the Mesozoic era, 75% of plant and animal species have been removed, including the dinosaurs. However, some species present in the Mesozoic era survived until today.

The Triassic era took place approximately 245 to 208 million years ago and was the first part of the Mesozoic era. Study of paleobotany helps scientists to determine the existence of this plant in history. Paleobotanists were able to determine that plants such as ginkgoes, ferns and conifers are land plants of the Triassic era. In addition, the new types of phytoplankton, such that dinoflagellates and coccolithophorids, made an appearance in the oceans and water.

Jurassic era took place of about 208 of 146 million years ago and has been the average period of the Mesozoic era. Dinosaurs evolved considerably during this period and depend on plants as a source of food. Seeds, such as cyads, plants has evolved rapidly.Ginkgo species also increased, although only Ginkgo balboa remains in force today.Species of conifers and pine trees is also increasing.

Cretaceous era took place from approximately 144 to 65 million years ago and was the last part of the Mesozoic era.Angiosperms are important in the world of the era of the Crétacé.Les plant development Angiosperms are plants with flowers, a large majority that require pollination by insects.Therefore the life of insects increases quickly too, as each dependent on another for the vie.Paléobotanistes believe dinosaurs ate of plants with flowers that was developed at the end of the Mesozoic era.

Although many plant of the Mesozoic era species became extinct some survived and other plant species are now believed "descendants" of the species. earlier today, coniferous trees and pine are similar in appearance and species of coniferous trees and pine-era mésozoïque.Plantes flowers are perhaps one of the most important of the Mesozoic era developments.

Scientists have not established a theory accepted why 75 per cent of plant and animal species have disappeared at the end of the era mésozoïque.Cependant, plants are essential to the survival of life on Earth in the Mesozoic, era as much as they are important for the survival of life on earth today.
