A fossil of Prototaxites, a colossal lifeform that once towered over ancient landscapes, is set to go on display at the National Museum of Scotland.
This enigmatic organism, which grew to more than eight metres tall, belonged to an "entirely extinct evolutionary branch of life", scientists believe. Initially thought to be a fungus, experts now suggest Prototaxites, which vanished approximately 360 million years ago, was neither plant nor fungus.
