location where the photograph was taken

04dec-01: This recognisable piece of tree trunk in cross-section is some 110–130 million years old, its sap now converted into glistening iron pyrites, the wood into brown coal (Lignite). Pieces of lignite can be found all along the shore in Swanage Bay, appearing from out of the rapidly eroding Wealden beds. (The coin is 25mm in diameter)
