During the Cretaceous era, trees varied significantly in size, with some reaching impressive heights. Notable examples include the coniferous trees, such as Araucarioxylon, which could grow up to 100 feet tall. Additionally, flowering plants began to diversify, contributing to a lush, dense canopy in many areas. Overall, the Cretaceous period featured a wide range of tree sizes, from small shrubs to towering giants.
It was part of the Mesozoic Era.
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.
The Paleocene, which is the first (oldest) part of the Cenozoic Era, as the Cretaceous was the last of the Mesozoic Era.
Modern trees primarily developed during the Mesozoic Era, particularly in the late Triassic to the early Cretaceous periods, around 250 to 145 million years ago. This era saw the emergence of gymnosperms, such as conifers, which became dominant in many ecosystems. Angiosperms, or flowering plants, began to appear in the late Cretaceous, further diversifying the types of trees we see today. The evolution of these plants significantly shaped terrestrial ecosystems and contributed to the development of modern forests.
