Description: 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! Sources: C. Kevin Boyce. "How green was Cooksonia? The importance of size in understanding the early evolution of physiology in the vascular plant lineage". Paleobiology, 34(2), 2008, pp. 179–194.
