Two new plant groups that emerged during the Mesozoic era were the conifers and the flowering plants (angiosperms). These groups diversified rapidly and became dominant in many terrestrial ecosystems during this time period.
In the Paleozoic period, animals such as trilobites, brachiopods, ammonites, and early vertebrates flourished. Plants included ferns, horsetails, and early seed plants. During the Mesozoic period, dinosaurs, marine reptiles like ichthyosaurs and plesiosaurs, as well as early mammals and birds were prevalent. Plants such as conifers, cycads, and ginkgoes thrived during this time.
Flowering plants first appeared around 140 million years ago during the Cretaceous period. They rapidly diversified and became the dominant group of plants, replacing many of the existing groups at the time.
Dinosaurs were the most successful group of animals during the Mesozoic era, dominating terrestrial ecosystems for millions of years. They evolved into a diverse range of shapes and sizes and were the top predators in many environments. The Mesozoic era also saw the rise of flowering plants and the expansion of marine reptiles.
Cycads and ginkgoes were important plants to the world's terrestrial ecosystems during the Mesozoic era, which lasted from around 252 million years ago to 66 million years ago. They were dominant plant groups during this time and played a significant role in the ecosystems of that period.
In the Mesozoic Era, during the cretaceous period
Precambrian
Events during the Mesozoic include the increasing dominance of dinosaurs. The Mesozoic is marked by the appearance of flowering plants.
Two new plant groups that emerged during the Mesozoic era were the conifers and the flowering plants (angiosperms). These groups diversified rapidly and became dominant in many terrestrial ecosystems during this time period.
Pines and Cypresses
In the Paleozoic period, animals such as trilobites, brachiopods, ammonites, and early vertebrates flourished. Plants included ferns, horsetails, and early seed plants. During the Mesozoic period, dinosaurs, marine reptiles like ichthyosaurs and plesiosaurs, as well as early mammals and birds were prevalent. Plants such as conifers, cycads, and ginkgoes thrived during this time.
According to the related link, the climate during the Mesozoic was warm; so warm that there were no ice caps at all, even at the poles. Plants grew in the warmth and moisture.
The Rocky Mts. Formed and Pangea started to break apart
