TXV24 Posted February 25, 2018 Share Posted February 25, 2018 Hi, This looks like a beach worn flint nodule which may have part of the structure of a fossil sponge or coral included. Flint originates from the Chalk and on the island is around 70 million years old. It forms from the remains of echinoids and sponges etc. Flint nodules are common on the Island's beaches especially on the western and south-eastern coasts where our Wealden strata is exposed. They were likely eroded from the chalk at some point during the Eocene/Oligocene when the central part of the Island was being uplifted by tectonic forces (which eventually eroded down to the Wealden), and may have been transported in Ice Age rivers. Hope this helps, Theo 3 Link to comment Share on other sites More sharing options...
