For humans, some of the most important seedless vascular plants lived and died about 300 million years ago. The remains of these ancient ferns, horsetails, and club mosses formed coal, a fossil fuel that we now extract from the Earth's crust. Hope this helps!
For humans, some of the most important seedless vascular plants lived and died about 300 million years ago. The remains of these ancient ferns, horsetails, and club mosses formed coal, a fossil fuel that we now extract from the Earth's crust.
The first seedless vascular plants evolved over 439 million years ago during the Silurian period. These early vascular plants developed the ability to synthesize lignin which gave them support.
Around 1,200 Million years ago but it wasn't until around 450 million years ago land plants formed.
They are the reason for coal. Millions of years ago, in the tropics, there were seedless vascular plants. When they died, they turned to coal.
Ferns are the most abundant group of seedless vascular plants, with about 12,000 living species. Recent research indicates that they may be the closest relatives to the seed plants. The fossil record indicates that ferns originated during the Devonian period about 350 million years ago and became abundant and varied in form during the next 50 million years. Their apparent ancestors had no broad leaves and were established on land as much as 375 million years ago.

Fossil fuels (coal, oil and natural gas) are formed from the remains of plants and animals. Three hundred million years' of pressure turned the organic matter into fuel.
Fossil records of seedless plants, such as ferns and horsetails, reveal their presence on Earth long before the evolution of seed-producing plants. Fossils show that these plants played a significant role in shaping ancient ecosystems and that they were widespread and diverse in the past. Studying these fossils helps us understand the evolutionary history and adaptations of seedless plants over millions of years.
