Plant Fossil Wood

What’s woodstone?

Nodules of hard limestone often form around pieces of fossil wood, particularly in the Lower Jurassic rocks around Lyme Regis. This type of stone is known as ‘woodstone’. You’ll see that attached to the wood are the shells of the oyster Inoceramus dorsetensis. Oysters would often grow on floating driftwood, keeping themselves above the anoxic (oxygen-depleted) sea bed. There are also other fossils on the wood, particularly ammonites and insects. 

This specimen was found by renowned collector, W.D.Lang – as you can see, he was extremely meticulous in his recording of strata details.
