Flowing plants, or angiosperms, are believed to have evolved during the Mesozoic Era, specifically in the Early Cretaceous period, around 140 million years ago. This marked a significant evolutionary development as angiosperms began to diversify and dominate terrestrial ecosystems, leading to a wide variety of flowering plants. Their emergence had a profound impact on the evolution of insects and other organisms, contributing to the complex interplay of life during this era.
There were actually three types of plants that evolved in the Mesozoic. Cycads and ginkgos evolved around the late Triassic and early Jurassic. The firsts flowering plants appear in the fossil record during the early Cretaceous period of the Mesozoic era.
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.

Pines and Cypresses
During the Mesozoic Era, flowering plants (angiosperms) were not yet common, as they emerged later in the era, around the Late Cretaceous. Additionally, many modern plant families, such as those found in tropical rainforests, were also absent or not fully developed during this time. Instead, the Mesozoic landscape was dominated by ferns, cycads, ginkgoes, and conifers.

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.
