Fungal Giants of the Devonian

~420 MYA (+/- 20 million)

Large upright fungal structures (e.g., Prototaxites)

Before trees towered over landscapes, giant fungus-like organisms rose several meters high. These early decomposers dominated some terrestrial ecosystems. Fungi were not merely background recyclers — they were visible pillars of early land life. These massive organisms—likely related to Prototaxites—may have stood over 6–8 meters tall. In a world still learning how to grow upward, fungi briefly held the skyline.
