Look familiar?
The rocks from Portland date back before the age of flowering plants. Most of the trees that we are familiar with today – the oak, ash, beech or hazel for instance – are flowering plants. The trees around in the Jurassic period were dominated by conifers. Look very closely at this extraordinarily well-preserved piece of foliage; it does in fact closely resemble a modern day Leylandii, the fast-growing trees often planted in people’s gardens.
