A classic ‘bird’s nest’
Local quarrymen called these peculiar structures ‘bird’s nests’ – but they are in fact the fossilised remains of a fern-like plant known as a cycad.
We have retained the name ‘cycad’ here because it is so popular and commonly used but strictly speaking they belong to a group known as the ‘Bennettitales’, which are a parallel branch to the cycads. Cycads and Bennettitales belong to the Gymnosperms which also includes conifer trees and the Ginkgo tree, which is another ‘classic’ living fossil that can be found in parks and gardens across the UK today.
