Summary

Description
English: Animated reconstruction of Cooksonia pertoni. The stems have been reconstructed as non-photosynthetic, according to Boyce (2008). The axes are imagined to be around 100μm in diameter. It is left to the viewer's imagination whether or not the thallus is associated with the Cooksonia axes!
