Highlight: Fossil Forest
As the Jurassic period drew to a close sea levels were falling. Shallow tropical seas gave way to coastal plains and for a brief period around 145 million years ago a forest grew here. The evidence for this is exposed to the east of Lulworth Cove on a rocky ledge known as the Fossil Forest.
Flowering plants had yet to evolve, so this forest was dominated by conifers, tree-ferns and cycads. When a lagoon rose to swamp the forest the trees died and were encased in limestone by sticky mats of algae. The strange rounded shapes this created are known as ‘algal burrs’. The broken trunks of trees are sometimes found preserved but none remain at the Fossil Forest site. They were probably all collected by Victorian visitors over 100 years ago. However, there are still plenty of algal burrs to see and they are amongst the strangest fossils on the Jurassic Coast.
Update: Fossil Forest access closed due to cliff fall, although some of the trees can still be viewed from the Coast Path along the cliff top.
Plans are in place to rebuild the steps to be able to reopen the path down to the fossil forest by Spring / early summer 2018.
The Coast Path is unaffected and you can still walk this section.
If you visit the Fossil Forest please not to try and collect any of the algal burrs or other fossils as the site is sensitive to damage.
