Introduction to Paleobotany
Paleobotany explores plant life from Earth's geological past. It deciphers the evolution of flora over eons, using fossilized remains to unravel pre-Mesozoic mysteries and plant progression.
Earliest Plant Life
Earliest Plant Life
The Silurian Period marked the advent of vascular plants. Around 430 million years ago, simple plants began terrestrial conquest, evolving from earlier, non-vascular forms like algae.
Devonian Forests Emerge
Devonian Forests Emerge
During the Devonian, 390 million years ago, Earth witnessed the first forests. Archaeopteris, an early tree with fern-like features, dominated these landscapes, foreshadowing modern tree structures.
Carboniferous Coal Swamps
Carboniferous Coal Swamps
The Carboniferous Period is renowned for vast coal-forming swamps. Giant horsetails, ferns, and clubmosses thrived, their remains now fueling our power stations as coal.
Permian Extinction Impact
Permian Extinction Impact
The Permian mass extinction, 252 million years ago, dramatically reshaped plant communities. Gymnosperms, including conifers, rose to prominence as many earlier plant groups vanished.
Triassic Recovery
Triassic Recovery
Post-extinction, the Triassic Period saw gymnosperms diversify and spread. This era gave rise to cycads and ginkgoes, plants that still have living representatives today.
Gymnosperms' Mesozoic Dominance
Gymnosperms' Mesozoic Dominance
Before the rise of flowering plants, gymnosperms reigned supreme. Their diversity peaked in the Jurassic, setting the stage for the later arrival of angiosperms.
