Types of extinct plants | plant-o-pedia

One of the most well known extinct trees by period are sigillara and lepidodendron which were both giant clubmosses that had thrived in the carboniferious period. Sigillaria was a tall tree growing up to 30-40 metres and lived through late carboniferious and died out in early permian. However, leipidodendron grew up to a very tall height of 100 metres making it an extremely tall tree but it only lived from early carboniferious to late caboniferious. Another type of plant that grew in the carboniferious period was called calamites. These were giant horsetail plants that had scale like leaves and a small trunk.

To the right is an artists impression of what a sigillaria mostly would have looked like if it was alive.
