Yes, trees did exist before dinosaurs. During the early periods of Earth’s history, such as the Devonian period (about 420 million years ago), plants began to evolve and spread across the land. These early plants were mostly non-vascular, meaning they didn’t have specialized tissues for transporting water and nutrients, but they laid the foundation for the development of more complex plant life.<div>
</div><div>By the Carboniferous period (about 359 to 299 million years ago), forests of tall, tree-like plants had emerged. These ancient trees, such as lycopsids, ferns, and early seed plants, formed dense forests in swampy environments. They thrived in warm, humid conditions with high levels of atmospheric carbon dioxide. Over time, these forests played a crucial role in shaping Earth’s climate and environment, eventually leading to the formation of coal deposits as their organic material was buried and compressed.</div>
